HELPP!!

One rental store charges a one time fee of $12 plus $3 per hour to rent a power washer. A
second rental store charges $15 plus $2 per hour to rent a power washer. For what number
of hours is the rental cost the same?

Answer 1

3 hours

Explanation:

First, we need to set up an equation with a variable representing the time.

12 + 3x = 15 + 2x

Then you solve.

12 + 3x = 15 + 2x

-2x-12 -2x-12

x = 3
