You work independently as a copier salesperson. Last month, you sold 26 printers at a cost of $1,750 each. The cost of goods sold for each printer is $975. Additional operating expenses include your salary ($3,000/month), advertising ($50/month), and office lease ($550/month). Use this information to calculate (a) your gross profit and (b) your net income.
To calculate the gross profit, we need to subtract the cost of goods sold (COGS) from the revenue generated by sales. The revenue generated by sales can be found by multiplying the number of printers sold by the selling price of each printer, which is $1,750.
Revenue generated by sales = 26 x $1,750 = $45,500
The cost of goods sold for each printer is $975, so the total cost of goods sold for all 26 printers is:
Total cost of goods sold = 26 x $975 = $25,350
Therefore, the gross profit can be calculated as:
Gross profit = Revenue generated by sales - Total cost of goods sold
Gross profit = $45,500 - $25,350
Gross profit = $20,150
The gross profit is $20,150.
To calculate the net income, we need to subtract all operating expenses from the gross profit. The operating expenses include your salary ($3,000/month), advertising ($50/month), and office lease ($550/month).
Total operating expenses = $3,000 + $50 + $550
Total operating expenses = $3,600
Therefore, the net income can be calculated as:
Net income = Gross profit - Total operating expenses
Net income = $20,150 - $3,600
Net income = $16,550
The net income is $16,550.
In summary, the gross profit is the revenue generated by sales minus the cost of goods sold, which in this case is $20,150. The net income is the gross profit minus all operating expenses, which in this case is $16,550.

Answer:
infinitely manyno solutionone solutionStep-by-step explanation:
You want to determine the number of solutions to three different systems of equations.
Standard formA linear equation is written in standard form when the coefficients are mutually prime, and the leading coefficient is positive:
ax +by = c . . . . . . GCF(a, b, c) = 1, a > 0
The equations are easiest to compare when they are all written in standard form.
Numbers of solutionsA system will have an infinite number of solutions when the equations are identical.
A system will have zero solutions when it reduces to ...
(non-zero constant) = 0
A system will have one solution when the equations are different.
System 1A factor of 2 can be removed from the first equation:
2x -3y = 5
A factor of 3 can be removed from the second equation:
2x -3y = 5
These equations are identical, so have infinitely many solutions.
System 2Multiplying the first equation by 2 gives ...
2y = -3x +6
Adding 3x, we have ...
3x +2y = 6
When we subtract the second equation from this, we get ...
(3x +2y) -(3x +2y) = (6) -(3)
0 = 3
These equations have no solution.
System 3These equations are already in standard form, and are different. This system has one solution.
(The exact solution is (x, y) = (0.48, 3.36).)

driven. If your total cost of a rental was $39. 80, how many miles
did you drive?
If the total cost is $39.80, then the number of miles driven is 66 miles.
If your total cost of a rental was $39. 80, how many miles did you drive?Here we know that a truck rental costs $20 plus $0.30 for each mile driven.
Then we can model this with a linear equation where the y-intercept is 20, and the slope is 0.30 (where the independent variable will be the number of miles driven).
Then the total cost is modeled by the linear equation:
y = 20 + 0.3*x
If the total cost is $39.80, then we can solve:
39.8 = 20 + 0.3*x
39.8 - 20 = 0.3*x
19.8/0.3 = x

Two containers designed to hold water are side by side, both in the shape of a cylinder. Container A has a diameter of 14 feet and a height of 11 feet. Container B has a diameter of 10 feet and a height of 19 feet. Container A is full of water and the water is pumped into Container B until Container B is completely full.
After filling Container B completely, there are approximately 209.56 cubic feet of water left in Container A.
How to solveContainer A:
Diameter = 14 feet
Radius = Diameter / 2 = 14 / 2 = 7 feet
Height = 11 feet
Volume of Container A = π * (7^2) * 11 ≈ 1,696.46 cubic feet
Container B:
Diameter = 10 feet
Radius = Diameter / 2 = 10 / 2 = 5 feet
Height = 19 feet
The volume of Container B = [tex]π * (5^2) * 19[/tex] ≈ 1,486.90 cubic feet
Now, let's find out how much water is left in Container A after filling Container B completely.
Water left in Container A = Volume of Container A - Volume of Container B
Water left in Container A ≈ 1,696.46 - 1,486.90 ≈ 209.56 cubic feet
So, after filling Container B completely, there are approximately 209.56 cubic feet of water left in Container A.

Why do we receive two answers in a projectile motion formula , a negative and a positive?
Answer:
Both solutions are valid, and depending on the context of the problem, one or both solutions may be useful in solving for different parameters, such as the maximum height or the time of flight of the projectile.
Step-by-step explanation:
In a projectile motion formula, such as the one that describes the height of an object in motion as a function of time, there are two solutions because the object can reach the same height at two different times during its trajectory.
The negative solution represents the time it takes for the object to reach its maximum height and then start falling back down to the ground. The positive solution represents the time it takes for the object to reach the same height on its way up.
So, both solutions are valid, and depending on the context of the problem, one or both solutions may be useful in solving for different parameters, such as the maximum height or the time of flight of the projectile.

The zeros of the function f(x) = (-x - 2)(-2x - 3) are x = -2 and x = -3/2, listed from least to greatest.
What are the zeros of the function?Given the function in the question:
f(x) = ( -x - 2 )( -2x - 3 )
To determine the zeros of the function f(x), we need to solve the equation f(x) = 0.

-x - 2 = 0
-x = 2
x = -2
( -2x - 3 ) = 0
-2x - 3 = 0

How to front end round 10,355?
Front-end rounding 10,355 to the nearest ten is 10,360.
Describe Rounding of Numbers?Rounding is the process of approximating a number to a specified degree of accuracy or precision. Rounding is useful when we want to simplify numbers or express them in a more manageable or meaningful way. There are various methods of rounding, such as rounding up, rounding down, and rounding to the nearest value.
To round a number to a specified degree of accuracy, we first identify the place value we are rounding to, such as units, tens, hundreds, etc. We then look at the digit in that place value and the digit to the right of it. If the digit to the right is 5 or greater, we round up by adding 1 to the digit in the place value we are rounding, and then replace all the digits to the right with zeros. If the digit to the right is less than 5, we round down by simply dropping all the digits to the right.
To front-end round a number, you look at the digit in the place value you are rounding to and round up or down based on the digit to the right of that place value.
To front-end round 10,355 to the nearest ten, we look at the tens place, which is the second digit from the right. The digit in the tens place is 5, which is greater than or equal to 5, so we round up.
To round up, we add 1 to the digit in the tens place and replace all the digits to the right with zeros. So, rounding up 10,355 to the nearest ten gives us:

a. The periodic deposit is $.
(Do not round until the final answer. Then round up to the nearest dollar as needed.)
The periodic deposit required to reach the financial goal of $1,000,000 in 45 years with a 6.75% annual interest rate compounded monthly is approximately $541.05.
And, Amount $292,593.00 comes from deposits and $707,407.00 comes from interest.
For the periodic deposit, we can use the formula:
P = (FV × r) / ((1 + r)ⁿ - 1)
where P is the periodic deposit, FV is the financial goal, r is the interest rate per period, and n is the total number of periods.
Using the given values, we get:
P = ($1,000,000 0.0675) / ((1 + 0.0675/12)^(45x12) - 1)
P ≈ $541.05
So, the periodic deposit required to reach the financial goal of $1,000,000 in 45 years with a 6.75% annual interest rate compounded monthly is approximately $541.05.
And, To determine how much of the financial goal comes from deposits and how much comes from interest, we can calculate the total amount of deposits made over the 45-year period:
Hence, Total deposits is,
P n = $541.05 (45 x 12)
≈ $292,593.00
Then we can subtract this amount from the financial goal to get the amount that comes from interest:
Amount from interest = FV - Total deposits
= $1,000,000 - $292,593.00
≈ $707,407.00
So , Amount $292,593.00 comes from deposits and $707,407.00 comes from interest.

For the points that satisfy the system of inequalities y < x² + 3 and y > x² - 4, we need to graph the two parabolas y = x² + 3 and y = x² - 4 and shade the region where the two graphs overlap.
The graph of y = x² + 3 is an upward-facing parabola that intersects the y-axis at (0, 3). The graph of y = x² - 4 is also an upward-facing parabola that intersects the y-axis at (0, -4).
We can see from the graphs that the region where y < x² + 3 and y > x² - 4 is the shaded region between the two parabolas. This region is bounded by the two lines y = x² + 3 and y = x² - 4.
To find a point that satisfies this system of inequalities, we can pick any point within this shaded region. For example, the point (0, 0) lies within the shaded region and satisfies both inequalities:
[tex]y = 0 < x^2+ 3 = 3\\y = 0 > x^2 - 4 = -4[/tex]
Therefore, the point (0, 0) is a solution to the system of inequalities.

On Team B 80% of the football players weigh more than 200 pounds. If 41 men are on the team, how many weigh more than 200 pounds?
Team B has 33 players that weigh more than 200 pounds.
How to calculate the percentage?To calculate the percentage, divide the amount by the total value and multiply the result by 100. The percentage is calculated using the formula: (value/total value)100%.
When 80% of the players weigh more than 200 pounds, 20% of the players weigh less than 200 pounds.
We can start by locating 20% of the players:
20% of 41 = 0.20 x 41 = 8.2
So we can guess that there are about 8 players weighing 200 pounds or fewer.
We may subtract this estimate from the total number of participants to obtain the number of players who weigh more than 200 pounds:
41 - 8 = 33
As a result, Team B has 33 players that weigh more than 200 pounds.

Which graph represents this equation? y = 3 2 x 2 − 6 x A. The graph shows an upward parabola with vertex (3, minus 4.5) and passes through (minus 1, 3.5), (0, 0), (6, 0), and (7, 3.5) B. The graph shows an upward parabola with vertex (2, minus 6) and passes through (minus 1, 7), (0, 0), (4, 0), and (5, 7) C. The graph shows an upward parabola with vertex (minus 3, minus 4.5) and passes through (minus 7, 3.5), (minus 6, 0), (0, 0), and (1, 3.5) D. The graph shows an upward parabola with vertex (minus 2, minus 6) and passes through (minus 5, 7), (minus 4, 0), (0, 0), and (1, 7)
The graph that represents the equation is:
The graph shows an upward parabola with vertex (2, -6) and passes through (-1, 7), (0, 0), (4, 0), and (5, 7).
Option B is the correct answer.
We have,
The equation y = (3/2)x² - 6x represents an upward parabola since the coefficient of x² is positive.
Now,
The vertex of the parabola.
x = -b/2a,
where a and b are the coefficients of x² and x, respectively.
So,
a = 3/2 and b = -6
x = -(-6)/(2(3/2)) = 6/3 = 2.
Plugging x = 2 into the equation,
We get y = 3/2(2)² - 6(2) = -6,
so the vertex is (2, -6).
We can eliminate options A and C since their vertices are not (2, -6).
Now,
To check which of the remaining options fits the equation, we can plug in the given points and see if they satisfy the equation.
Option B gives:
When x = -1, y = 3/2(-1)² - 6(-1) = 7
When x = 0, y = 3/2(0)² - 6(0) = 0
When x = 4, y = 3/2(4)² - 6(4) = 0
When x = 5, y = 3/2(5)² - 6(5) = 7.5
So option B fits the equation, and is the graph that represents
y = (3/2)x² - 6x.
Therefore,
The graph that represents the equation is:
The graph shows an upward parabola with vertex (2, -6) and passes through (-1, 7), (0, 0), (4, 0), and (5, 7).
