    A repair bill for your car is $553. The parts cost $265. The labor cost is $48 per hour. Write and solve an equation to find the number of hours of labor spent repairing the car

    Set up the cost equation C(h) where h is the number of labor hours:
    C(h) = Labor Cost per hour * h + Parts Cost

    We're given C(h) = 553, Parts Cost = 265, and Labor Cost per Hour = 48. So we plug these in:
    48h + 265 = 553

    To solve this equation for h, we type it in our math engine and we get:
    h = 6 hours
