Pansy · Answer 1

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
