If two parking attendants can wait on 8 vehicles per minute and vehicles are leaving the parking garage randomly at an average rate of x vehicles per minute, then the average time T' in minutes spent waiting in line and paying the attendant is given by the formula where 0 ≤ x  A graph of T is shown in the figure.

(a) Evaluate 7(4) and 7(7.5). Interpret each of these results.

(b) What happens to the wait as vehicles arrive at an average rate that approaches 8 cars per minute?
