Answer:
Madison worked 7.5 hours before school and 15 hours after school last week.
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Rate per hour of Madison's job before school = US$ 11.50
Rate per hour of Madison's job after school = US$ 11.75
Earnings last week = US$ 262.50
Hours she worked before school = x
Hours she worked after school = 2x (she works twice as many hours after school)
2. How many hours did Madison work at each job last week?
For solving for x, we will use the following equation:
262.50 = 11.50x + 11.75 (2x)
262.50 = 11.50x + 23.50x
262.50 = 35x
x = 262.50/35
x = 7.5 ⇒ 2x = 15
Madison worked 7.5 hours before school and 15 hours after school last week.
