Answer:
It took 5 hours to repair the car
Explanation:
An auto repair shop charged a customer $349 to repair a car.
The bill listed $99 for parts and the remainder for labor.
The cost of labor is $50 per hour. If the number of hours it took to repair the car is x, then:
99 + 50x = 349
To find the number of hours it took to repair the car, we need to find x:
50x = 349 - 99
50x = 250
x = 250 / 50 = 5 hours
It took 5 hours to repair the car.
