CompTech Solution purchases one model of computer at a wholesale cost of $400 per unit and resells it to end consumers. The annual demand for the company’s product is 500,000 units. Ordering costs are $1,000 per order and carrying costs are $80 per computer, including $30 in the opportunity cost of holding inventory.

Required

1. Compute the optimal order quantity using the EOQ model.
2. Compute (a) the number of orders per year and (b) the annual relevant total cost of ordering and carrying inventory.
3. 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 $50, not $80. How would this affect the EOQ amount and the actual annual relevant cost of ordering and carrying inventory?
4. What is the cost impact on the company of excluding the opportunity cost of carrying inventory when making EOQ decisions? Why do you think the company currently excludes the opportunity costs of carrying inventory when evaluating the manager’s performance? What could the company do to encourage the manager to make decisions more congruent with the goal of reducing total inventory costs?
