    43 minutes.

    Step-by-step explanation:

    f (x) is the time in minutes that a customer will wait when x cars are ahead of the customer.

    If a customer is 5th in the line, it means there are 4 cars ahead of that customer.

    So, the time that customer waits is equal to f (4)

    f (4) = 7 * 4 + 15

    f (4) = 28 + 15

    f (4) = 43 minutes
