A
Interpretation: The order quantity that should be used in a continuous review inventory system is to be calculated.
Concept Introduction: Economic order quantity (EOQ) is the order of quantity that decreases the total holding cost and ordering costs for the annum.
B
Interpretation: The reorder point that should be used is to be calculated.
Concept Introduction: Reorder point assures that there should be a balance in stock. It avoids unnecessary carrying cost of the stock.

A particular musky lure has been very popular with local fishermen as well as those who buy lures on the Internet from Osprey Sports. The cost to place orders with the supplier is $30/order; the demand averages 4 lures per day, with a standard deviation of 1 lure; and the inventory holding cost is $1.00/lure/year. The lead time from the supplier is 10 days, with a standard deviation of 3 days. It is important to maintain a 97 percent cycle-service level to properly balance service with inventory holding costs. Osprey Sports is open 350 days a year to allow the owners the opportunity to fish for muskies during the prime season. The owners want to use a continuous review inventory system for this item.a.
