Questions 37 and 38 refer to the following information. If shoppers enter a store at an average rate of $r$ shoppers per minute and each stays in the store for an average time of $T$ minutes, the average number of shoppers in the store, $N$, at any one time is given by the formula $N = r T$. This relationship is known as Little's law. The owner of the Good Deals Store estimates that during business hours, an average of $3$ shoppers per minute enter the store and that each of them stays an average of $15$ minutes. The store owner uses Little's law to estimate that there are $45$ shoppers in the store at any time. Little's law can be applied to any part of the store, such as a particular department or the checkout lines. The store owner determines that, during business hours, approximately $84$ shoppers per hour make a purchase and each of these shoppers spends an average of $5$ minutes in the checkout line. At any time during business hours, about how many shoppers, on average, are waiting in the checkout line to make a purchase at the Good Deals Store?
