The first thing we must do for this case is to define the variables:
x = the amount earned
y = the money saved
The equation of the line that adapts to this problem is given by:
y = (1/5) x
Let's check:
For x = 20 $ we have:
y = (1/5) (20)
y = 4 $
Answer:
The slope of Mike's graphed line will be:

Yes they are! The square root of 36 is 6 and the square root of 25 is 5.
Answer:
<u>The original cost of the printer before adding the tax was $ 173.98</u>
Step-by-step explanation:
Total cost of the color printer, including tax = $ 186.16
Tax rate = 7%
Original cost of the printer, before tax = x
For answering the question, let's use the Rule of Three Simple, this way:
Percentage Value
107% 186.16
100% x
x * 107 = 186.16 * 100
107x = 18,616
x = 18,616/107
x = 173.98
<u>The original cost of the printer before adding the tax was $ 173.98</u>
172.6 rounded to the nearest hundred place = 200
39 rounded to the nearest ten place= 40
200/40= 5
The answer is 5. Hope this helps!
