Recall "Tommy's Dresses to go" case. Three years after, this company still
rents designer dresses to customers, but it has managed to streamline its
internal processes and expand to different segments of demand. Now,
customers can rent clothes for anywhere between 1 days to 30 days, and
each customer is sent only one (1) dress (instead of 2 dresses described in the
case). The company alsó takes only 13 number of days to turn around a dress
(i.e., this the duration starting with return from a customer, to again being
rented out to a customer). The current demand is an average of 1,000
customers per day, and the company owns total of 30 thousand dresses.
What is the average rental duration? (i.e., what is the average number of days,
a customer keeps a dress).
