B$.$ Suppose that the store manager is concerned that stockouts might cause a loss of future business. To explore this idea, the store manager feels that it is appropriate to assign a stockout cost of $$5$ per bagel that is demanded but not filled. $($Customers frequently purchase more than one bagel at a time. This cost is per bagel demanded that is not satisfied rather than per customer that does not receive a complete order.$)$ Given the additional stockout cost, how many bagels should the store have at $3$ p$.$m$.$ to maximize the store$$s expected profit?
