    The cost to rent a construction crane is 450 per day plus 150 per hour. What is the maximum number of hours the crane can be used each day if the rental cost is not to exceed 1650 per day?

    Set up the cost function where h is the number of hours:
    C(h) = 150h + 450

    We want C(h) <= 1650:
    150h + 450 <= 1650

    Using our equation/inequality solver, we get:
    h <= 8
