Consider a four-step serial process with the number of workers at each step and processing times given in the list below.
	Process Step	Number of Workers	Time per Customer (in Minutes)
	1	1	7
	2	3	16
	3	3	8
	4	3	5
	Assuming that the process starts out empty and is worker-paced, how long will it take (in minutes) to serve 26 customers? (Round to nearest minute)

At a car wash, services offered include vacuum, wash and detail. The vacuum process has a demand of 13 customers per hour. The wash process has demand of 8 customers per hour. The detail process has a demand of 14 customers per hour. There are 3 employees staffing the vacuum process and each has a capacity of 10 customers per hour. The wash process is staffed by 3 employees, who can each serve 5 customers per hour. The detail is performed by 4 employees, each of whom can serve 6 customers per hour.
