CWD Office Supplies sells Printers, which it orders from Kajama Inc in Japan. Because of shipping and handling costs, each order must be for 5 printers. Because of the time it takes to receive an order, the company places an order every time the present stock drops to 5 Printers. It costs $50 to place an order. It costs the company $500 in lost sales when a customer asks for a Printer and the warehouse is out of stock. It costs $100 to keep each Printer stored in the warehouse. If a customer cannot purchase a Printer when it is requested, the customer will not wait until one comes in but will go to a competitor.The following probability distribution for demand for Printer has been determined:

Lead Time: Time to Receive an Order (wk)	Probability	Cumulative Probability	Random Number Mapping
1	0.60	0.60	00-59
2	0.20	0.80	60-79
3	0.20	1.00	80-99
