To sell 300 notebooks and 120 pens quickly, a store decided to create two types of gift sets. one set is to include 2 notebooks and 1 pen, and the other will consist of 1 pen and 3 notebooks. the first set will be sold for $8, while the second will be sold for $11.50. it is unprofitable to sell more than 20 of any gift set. how many gift sets of each type must the store sell to obtain the biggest possible income?

Answers

The store must sell 60 of each set each to obtain the biggest possible income

How to determine the number of each gift set?

The given parameters can be represented using the following table:

                        Set 1        Set 2     Available

Notebook         2                3         300

Pen                   1                  1          120

Selling price     8               11.5

Using the above data values, we have:

Objective function: Max P = 8x + 11.5y

Subject to:

2x + 3y ≤ 300

x + y ≤ 120

Next, we plot the graph of the above inequalities (see attachment)

From the attached graph, we have:

(x,y) = (60,60)

Hence, the store must sell 60 of each set each to obtain the biggest possible income

The total time spent in minutes is 110 minutes

How to determine the total time?

The given parameters are:

Erica = 1 hour, 15 minutesSean = 35 minutes

The total time is calculated as:

Total = Erica + Sean

So, we have:

Total = 1 hour, 15 minutes + 35 minutes

1 hour = 60 minutes

So, we have:

Total = 60 minutes + 15 minutes + 35 minutes

If triangle ABC has vertices A(1, 2), B(-1, -1), and C(0, -2), which of the following coordinates is B’ of the dilation using the scale factor 4?

Answers

Answer: B'(-4, -4)

Given : A(1, 2), B(-1, -1), C(0, -2)

"Focusing on B coordinates"

If the points are dilated with a scale factor of 4

Then new coordinates : (-1, -1) × 4 = B'(-4, -4)

Answer:

B' = (-4, -4)

Step-by-step explanation:

Dilation:  A type of transformation that makes the pre-image larger or smaller without changing its shape.

Center of a dilation:  a fixed point about which all points are dilated.

Given:

A = (1, 2)B = (-1, -1)C = (0, -2)Scale factor = 4

For dilation when the center of dilation is the origin (0, 0), simply multiply the coordinates of the vertices of the pre-image by the given scale factor to find the image under dilation:

Therefore:

A' = (1 x 4, 2 x 4) = (4, 8)

B' = (-1 x 4, -1 x 4) = (-4, -4)

C' = (0 x 4, -2 x 4) = (0, -8)

Answers

The rate of compounding on the investment is 20%.

What is the rate of compounding?
When an amount compounds annually, it means that both the amount invested and the interest accrued increases in value once a year.

The formula that can be used to determine the rate of compounding is: (FV / PV)^(1 /n)

Where:

FV = future value = 125,000 + 91,000 = 216,000PV = present value = 125000n = number of years - 3

Ezra has a square brick patio. he wants to reduce the width by 6 feet and

increase the length by 6 feet.

What is the area of the square?

The area of the square is the measure of the space occupied by it. It is equal to the product of the measure of its two sides.

We need to write the expression for the new patio and the area of the new patio if the original patio measures 13 feet by 13 feet.

let x be the measure of the side of a square.

The length increased by 6 ft, so the new length=x+6.

The width decreased by 6 ft, so the new width=x-6.

The area is the product of length and width, so the new area is

l×w = (x+6)×(x-6)

Since the original side is 13 ft, the new length is 13+6 = 19 ft, and the new width is 13-6=7 ft.

So, the area is (19 ft)×(7 ft) = 133 ft²

Hence, the area of the new patio if the original patio measures 13 feet by 13 feet is 133 ft².

Now

y=6(3)+2y=18+2y=20

C

Answer:

C.  y = 20

Step-by-step explanation:

Given system of equations:

[tex]\begin{cases}3y = 18x + 6\\y = 2x + 14\end{cases}[/tex]

Multiply the second equation by 3:

[tex]\implies (3)y=(3)2x+(3)14[/tex]

[tex]\implies 3y=6x+42[/tex]

Subtract this from the first equation to eliminate 3y:

[tex]\begin{array}{r l}3y & = 18x+6\\-\quad3y&=6x+42\\\cline{1-2}0&=12x-36\end{array}[/tex]

Solve the resulting equation for x:

[tex]\implies 12x-36=0[/tex]

[tex]\implies 12x=36[/tex]

[tex]\implies x=3[/tex]

Substitute the found value of x into the original second equation and solve for y:

1 family member gets 127 text messages

3 family members get 125 text messages each
1 family member gets 126 text messages

Answers

Answer:

3 family members get 126 text messages each

1 family member gets 127 text messages

Step-by-step explanation:

If you were finding the exact division of texts, 505 texts / 4 people, you would end up with 126.25 texts.

However, you can't get 0.25 of a text. If we take back each family member's 0.25 text, they will all be left with 126 texts (with an extra text leftover)

This extra text is considered the "remainder", meaning the amount left over when a number is divided [when it doesn't go into the larger number evenly]. The only importance/relevancy of a remainder is when a value cannot be split, such as a dog or a text.

So, we can give each family member 126 texts, and then we can give one family member an additional text, so that all texts are distributed.

This means that 3 family members get 126 texts, and 1 family member gets 127 texts

hope this helps!!
