Reiko started a business selling home medical supplies. She spent $6500 to obtain her merchandise, and it costs her $550 per week for expenses. She earns $900 per week for general expenses.
What is the minimum number of weeks it will take for Reiko to make a profit?
a.) 900w ≥ 6500 + 550w
b.) 900w < 6500 + 550w
c.) 900w > 6500 + 550w
d.) 550w > 6500 + 900w
Answers
Answer:
C
Step-by-step explanation:
$6500 is a one time purchase so there is no variable attached.
$550 and $900 per week is reoccurring so there will be a variable attached.
Since $900 is what she is making each week, this will be separate from her costs (can eliminate D).
To make a profit, her amount earned will need to be greater than her expenses, so the answer is C.
please someone help me. Im giving brainliest!!
Answers
Answer:
False
Step-by-step explanation:
You'll add 10 to both sides. you'll end up with
2x =24.
Now, you divide 2 on both sides.
x=12
We have
2x-10=14
Now we shift 10 to the RHS
2x=14+10
2x=24
Now we need to substitute x
x=24/2
x=12
So the answer is false as we have only one solution for this equation

Kathy is a scientist who is working in a remote part of Australia. She earns a salary of $86 840 plus a weekly allowance of $124.80 for working under extreme and isolated conditions. Calculate Kathy’s fortnightly pay.
Answers
Answer:
$3589.60
Step-by-step explanation:
Salary per fortnight {52 weeks in a year; 2 weeks in a fortnight}
= 86840 / 52 × 2
= 3340
Allowance per fortnight = 124.80 × 2 = 249.60
Therefore, total fortnightly pay is:
3340 + 249.60 = 3589.60
What is the net pay?

Social Security deduction $9.65
Other deductions $6.37

$162.14
Answers
Net pay for the individual is $132.83
Given that;
Number of hour worked = 27.25
Per hour pay = $5.95
Federal tax deduction = $13.29
Social Security deduction = $9.65
Other deductions = $6.37
Find:
Net pay
Computation:
Net pay = [(27.25)(5.95)] - 13.29 - 9.65 - 6.37
Net pay = [(27.25)(5.95)] - 13.29 - 9.65 - 6.37
Net pay = 162.1375 - 29.31
Net pay = 132.8275
Net pay = $132.83

The ranges for the box plots are the same, but their interquartile ranges are different.
Answers
Answer:
to find range of interquartile sets of data
you see 5 vertical lines 1 is start point 2 is start of 2nd quartile 3 is start of 3rd quartile and also represents the median. the 4th start of 4th quartile and 5th is very end point.
Therefore the interquartile is from start line 2 to start line 4
apply to each by if it says 10 and 34 then we show workjings 34-10 = 24 and that is the range once we deduct data from each other.
Therefore full range is start line 1 to end line 5
if this says 2 to 45 then full range is 45-2 = 43 and apply to each boxplot.

Order the following numbers from least to greatest 1/2, -0.67, -2/5, 0.54, -1.2
Answers
Answer:
-1.2; -0.67; -2/5; 1/2; 0.54
Step-by-step explanation:
because there are negative numbers, we put those first. the bigger the number behind the negative is, the smaller it is
-1.2 is the only negative with a ones place so it goes first
-0.67 comes right before -2/5, or -0.4
then we move into the positive numbers: 1/2 and 0.54
1/2 is 0.5, which is less than 0.54
so the order is -1.2; -0.67; -2/5; 1/2; 0.54

The sum of three numbers is 21. The second number is two more than twice the first number. The second number is three times the third number. What are the numbers?
Answers
Answer:
The numbers are:
5, 12 and 4
Step-by-step explanation:
a + b + c = 21 Eq. 1
b = 2a +2 Eq. 2
b = 3c Eq. 3
From Eq. 2:
b - 2 = 2a
(b-2)/2 = a Eq. 4
From Eq. 3:
c = b/3 Eq. 5
Replacing Eq. 4 and Eq. 5 in Eq. 1:
(b-2)/2 + b + b/3 = 21
3(b-2)/6 + 6b/6 + 2b/6 = 126/6
3(b-2) + 6b + 2b = 126
(3*b + 3*-2) + 8b = 126
3b - 6 + 8b = 126
11b = 126 + 6
11b = 132
b = 132/11
b = 12
from Eq. 4
(b-2)/2 = a
(12-2)/2 = a
10/2 = a
a = 5
from Eq. 5
c = b/3
c = 12/3
c = 4
Check:
from Eq. 1
a + b + c = 21
5 + 12 + 4 = 21

This results in 18x^7 fr the top term

An arcade charges a flat fee for $7 to enter and then $1.25 per ticket to play games. Write an equation that models the charges (C) in terms of the number of tickets (t) that you use:
Answers
Answer:
C = 7 + 1.25t
Step-by-step explanation:
7 remains constant
1.25 changes according to t
Answer:
C(t ) = 1.25t + 7
Step-by-step explanation:
We can establish the following equation:
C(t ) = 1.25t + 7
Where:
C(t ) = represents the total cost relative to the t number of tickets used
t = number of tickets used to play games
1.25 = cost per ticket to play games
7 = flat fee to enter the arcade
