Question

Drey makes $10 an hour plus $15 an hour for every hour of overtime. Overtime hours are any hours more than 40 hours for the week.
Part A: Create an equation that shows the amount of wages earned, W, for working x hours in a week when there is no overtime. (3 points)

Part B: Create an equation that shows the amount of wages earned, S, for working y hours of overtime. Hint: Remember to include in the equation the amount earned from working 40 hours. (3 points)

Part C: Drey earned $490 in 1 week. How many hours (regular plus overtime) did he work?

Answer 1

Part A:  W = 10x

Part B:  S = 400 + 15y

Part C:  490 = 400 +15y
              -400  -400
              90 = 15y
              6 = y,  so he worked a total of 46 hours.
