Unit 7 Review - Systems

Bill earns $8.25 per hour parking cars for a restaurant. He also earns $85 each week that he works.

What equation represents Bill's earnings if h is the number of hours and E is the earnings for one week?

• E = 8.25h + 85

• E = 85h + 8.25

• E = 8.25h - 85

• E = 85 - 8.25h
