Perry sells TVs at an electronics store. He makes a 15% commission for every TV he sells. How much would he have to sell a single TV for to make a $72 commission?

$480

Step-by-step explanation:

Perry makes 15% commission for each TV he sells.

How much would he have to sell a TV to get $72

First of all, let's call the unknown variable x

So 15% of x= $72

Mathematically, this would be represented as 15/100 * x= 72

15/100x= 72

Breaking down further,

15/100 can be broken down to 3/20

3/20x= 72

So to find the value of x, we divide both sides by 3/20

x= 72 ÷ 3/20

x= 72 * 20/3 (using the law of indices)

x= 1440/3

x= $480 dollars.

So, Perry would have to sell a TV for $480 to make a $72 commission.

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3
