Answer:
87 total hours.
Step-by-step explanation:
The equation 456/12 Gives you how many hours Sienna worked. (38)
642-480 will give you how much money Serena made off of Just OT (162)
162/18 = 9 (9 is how many overtime hours Serena worked.)
Serena worked her normal 40 hours, then worked over time, so you have to add 40 to the equation.
9+40+38 = 87
Serena and Sienna worked 87 total hours.
