A bakery that orders cartons of bread mix has used an EOQ model to determine that an order quantity of 90 cartons per order is economically optimal. The bakery needs 150 cartons per month to meet demand. It takes L days for the bakery’s supplier to deliver an order. When should the bakery place its orders when L = 2, when L = 5, and when L = 10? (Assume that the bakery and its supplier both work 7-day weeks and that there are 30 days per month.)
