Marvin earns $7.25 per hour at his summer job. He wants to buy a video game system that costs $166.75. Enter an equation to model the relationship between the number of hours worked h and the amount earned e

7.25h = e

If e = $166.75, h = 23 hours

Step-by-step explanation:

7.25h = e

However many hours he works, he'll earn 7.25 times that number.

If he wants to know how many hours he must work to get the video game system where e = 166.75, we model this with

7.25h = e

7.25h = 166.75

Divide both sides by 7.25.

h = 23 hours
