Answer:
<em>Martin saved $75 on the television because of the sale</em>
Step-by-step explanation:
<u>Equations</u>
Let's call x=the original price of the television (before discount).
The television had been on sale for 25% off, this means the discount was:
25% of x =
= 0.25x
The sale price was the original price minus the discount:
x - 0.25x = 0.75x
This is what Martin paid, thus:
0.75x = 225
Dividing by 0.75:
x = 225 / 0.75
x = $300
The original price of the television was $300, and the discount was:
0.25*$300 = $75
Martin saved $75 on the television because of the sale
Answer:
represents the radius (in cm) of a circle whose circumference is 15 cm
if
, then a represents the circumference (in cm) of a circle whose radius is 15cm
Step-by-step explanation:
In a circle the following relationship can be posed:

Let g be a function that determines the radius of the circle from the value of its circumference, so, you have:

Thus,
represents the radius (in cm) of a circle whose circumference is 15 cm. You have to
.
On the other hand, if
, then
represents the circumference (in cm) of a circle whose radius is 15cm. You have to
