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? Show your work. (4 points)

Answer 1

A. W = 10x

B. S = 10x + 15y...or S = 10x + 15(x - 40)

C. 10(40) + 15y = 490
      400 + 15y = 490
      15y = 490 - 400
      15y = 90
      y = 90/15
      y = 6

so he worked 40 regular hrs and 6 overtime hrs
