Marco earns $16 an hour plus $21 an hour for every hour of overtime. overtime hours are any hours more than 35 hours for the week. part a: create an equation that shows the amount of money earned, e, 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, t, for working y hours of overtime. hint: remember to include in the equation the amount earned from working 35 hours. (3 points) part c: marco earned $602 in 1 week. how many hours (regular plus overtime) did he work? show your work. (4 points)

Given:
16 per hour - regular hours
21 per hour - overtime hours
35 hours - total number of regular hours

Part A: Create an equation that shows the amount of money earned, E, for working x hours in a week when there is no overtime.

E = 16x
where x ≤ 35

Part B: Create an equation that shows the amount of wages earned, T, for working y hours of overtime.

T = 21(y-35)

Part C: Marco earned $602 in 1 week. How many hours (regular plus overtime) did he work? 

E + T = 602

16x + 21(y-35) = 602
16(35) + 21y - 735 = 602
560 + 21y - 735 = 602
21y = 602 - 560 + 735
21y = 777
y = 777/21
y = 37

Regular hours = 35 hours ; Overtime = 2 hours

To check

16(35) + 21(2) = 602
560 + 42 = 602
602 = 602
