**Question 2**

The home appliance department of a large department store is using a lot size-reorder point system to control the replenishment of a particular model of coffee machine. The store sells an average of 12 machines each week. Weekly demand follows a normal distribution with variance 9. The store pays $20 for each coffee machine, which it sells for $75. Fixed costs of replenishment amount to $28. The accounting department recommends a 20 percent interest rate for the cost of capital, including storage and breakage of each item. If a customer demands the coffee machine when it is out of stock, the customer will generally go elsewhere. Loss-of-goodwill costs are estimated to be about $25 per coffee machine. Replenishment lead time is three months. Assume 1 year = 48 weeks.

If lot sizes are based on the EOQ formula, what lot size and reorder level should be used for the coffee machine?

- Q = 90
- R = 192
