Correct Answer: C
Given that demand is constant and the EOQ is 2,500 units, the average inventory level-1 without regard to safety stock is 1,250 units 2,500 - 2). Adding safety stock results in an average level of 1,750 units 1,250 + 500). Given also that annual holding costs are 25% of average inventory and that unit cost i s U $4, total annual holding cost i s U $1 ,750 [(1 ,750 units : $4) 25%]. Using an EOQ analysis assuming a constant demand), it is determined that the optimal order quantity is 2,500. The company desires a safety stock of 500 units. A five day lead time is needed for delivery. Annual inventory holding costs equal 25°!a of the average inventory level. It costs the company US $4 per unit to buy the product, which it sells for US $8. It costs the company US $150 to place a detailed order, and the monthly demand for the product is 4,000 units.
