    The cost of hiring a car for a day is $60 plus 0.25 cents per kilometer. Michelle travels 750 kilometers. What is her total cost

    Set up the cost function C(k) where k is the number of kilometers traveled:
    C(k) = 60 + 0.25k

    The problem asks for C(750)
    C(750) = 60 + 0.25(750)
    C(750) = 60 + 187.5
    C(750) = 247.5
