Prоblem 3. (Q,R) mоdel.(30pts) A gift stоre is selling а GT brаnded cаp for $20 each. The store buys the GT caps from its supplier for $15 each and it costs $25 to place an order (fixed cost). It takes one month to deliver the order from the supplier and the holding cost for each cap is $0.25. When a customer arrives with demand for the cap, the penalty associated with not having a GT cap is $4 per cap.
