Inventory decision, opportunity costs. Best Trim, a manufacturer of lawn mowers, predicts that it will purchase 204,000 spark plugs next year. Best Trim estimates that 17,000 spark plugs will be required each month. A supplier quotes a price of $9 per spark plug. The supplier also offers a special discount option: If all 204,000 spark plugs are purchased at the start of the year, a discount of 2% off the $9 price will be given.
Best Trim can invest its cash at 10% per year. It costs Best Trim $260 to place each purchase order.

Rugged Outfitters purchases one model of mountain bike at a wholesale cost of $520 per unit and resells it to end consumers. The annual demand for the company’s product is 49,000 units. Ordering costs are $500 per order and carrying costs are $100 per bike per year, including $40 in the opportunity cost of holding inventory.
Q. Assume that when evaluating the manager, the company excludes the opportunity cost of carrying inventory. If the manager makes the EOQ decision excluding the opportunity cost of carrying inventory, the relevant carrying cost would be $60, not $100. How would this affect the EOQ amount and the actual annual relevant cost of ordering and carrying inventory?
Ottis, Inc., uses 640,000 plastic housing units each year in its production of paper shredders. The cost of placing an order is $30. The cost of holding one unit of inventory for one year is $15.00. Currently, Ottis places 160 orders of 4,000 plastic housing units per year.
REQUIRED:
Compute the annual ordering cost.
Compute the annual carrying cost.
Compute the cost of Ottis’s current inventory policy. Is this the minimum cost? Why or why not?
