    computer models

    A food store has an average of 220 customers arriving per hour during peak
    shopping hours. During these peak periods all eight checkout counters will be open and operating with
    a capacity of serving an average of 35 customers per hour per counter. All checkout counters are
    identical.
    a). What proportion of the time would all the checkout counters and waiting lines be empty of
    customers?
    b). How long would customers wait in line on the average?
    c). How many customers would be waiting in each line on the average?

    The answer is the same as for the car wash problem except now there are 8 ques and you need to distribute the new arrivals evenly amoung them.
