    The bill for the repair of a car was $294. The cost of parts was $129, and labor charge was $15 per hour. How many hours did it take to repair the car? Write a sentence as your answer.

    Let h be the number of hours. We have:
    15h + 129 = 294

    To solve this equation for h, we type it in the search engine and we get:
    h = 11
