Answer:
Inspection fee = $50
h = 2 hours
Step-by-step explanation:
Let
x = the inspection fee
Charge per hour = $22
Number of hours = 4
A customer with a coupon for 40% off the inspection fee
This means the customer paid 60% of the inspection fee
118 = 60% of x + 22(4)
118 = 0.6x + 88
118 - 88 = .6x
30 = .6x
x = 30/0.6
x = $50
Inspection fee = x = $50
How many hours are worked when a customer pays $94 without a coupon?
94 = 50 + 22h
94 - 50 = 22h
44 = 22h
h = 44/22
h = 2 hours
