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: Andrew earned $330 in 1 week. How many hours (regular plus overtime) did he work? Show your work. (4 points)

Answer 1

Part A: W=6x
Part B: S=6(40)+9y
Part C: 330=6(40)+9y... 6(40)=240... 330-240=90...

9y=90... 9y/9= y... 90/9=10, therefore y=10

Andrew worked 40 regular hours and 10 overtime hours.
