A billiard ball maker must place orders for resin, a raw material for billiard balls. It uses resin at a rate of 80 kilograms each day, and incurs a cost of $0.5 per kilogram per day to hold inventory. The ordering cost is $200 per order. Lead time for delivery is 4 days. Assume 365 day in a year. If the company uses the order quantity of 500 unit, what is the difference between the number of orders per year for this scenario and the optimal number of orders per year associated with the minimum total cost of ordering and inventory holding?
