Problem #3 Customers at Joe's Office Supply Store demand an average of 7,500 desks per year. Each time an order is placed, an ordering cost of $500 is incurred. The annual holding cost for a single desk is 25% of the $300 cost of a desk. Suppose two weeks elapse between the placement of an order and the arrival of the order. In parts (a)-(e), assume that NO shortages are allowed. (a) Each time an order is placed, how many desks should be ordered? (b) How many orders should be placed each year? (c) Determine the total annual costs of meeting the customers' demand for desks. (d) Determine the reorder point. (e) If the lead time were five weeks, what would be the reorder point? (52 weeks - 1 year) (f) How would the answers to part (a) and (b) change if shortages were allowed and a cost of $100 is incurred if Joe's is short one desk for one year
