Question

Matt wants to hire a company to detail his car. Company A charges $15+17h where h represents the hours it takes to detail the car. Company B charges $20h where h represents the hours it takes to detail the car. For what number of hours is the total amount charged for detailing the car the same for both companies?

Answer 1

5 hours

Explanation:

Answer 2

5 hours

Explanation:

First, you set the equations equal, so 20h=17h+15

Second, you isolate the h, so you would subtract 17h from both sides, giving you 3h=15

Last, you divide both sides by 3 giving you h=5, meaning the companies charge the same price after 5 hours.
