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).
