Problem 31
Question
An automobile repair shop charged a customer \(\$ 448,\) listing \(\$ 63\) for parts and the remainder for labor. If the cost of labor is \(\$ 35\) per hour, how many hours of labor did it take to repair the car?
Step-by-Step Solution
Verified Answer
It took 11 hours to repair the car.
1Step 1: Calculate Total Labor Cost
Subtract the cost of the parts from the total cost. This can be formulated as follows: Total Labor Cost = Total Cost - Cost of Parts = \$448 - \$63 = \$385.
2Step 2: Calculate Labor hours
Divide the total labor cost by the cost of labor per hour to get the number of hours it took to repair the car. This can be formulated as follows: Labor hours = Total Labor Cost / Labor Cost per Hour = \$385 / \$35 = 11 hours.
