1. A billiard ball maker must place orders for resin, a raw material for billiard balls. It uses resin at a rate of 120 kilograms each day, and incurs a cost of $0.4 per kilogram per day to hold inventory. The ordering cost is $150 per order. Lead time for delivery is 4 days. Assume 365 day in a year. If the order quantity is 1,200 kilograms, what is the ratio of the average inventory level in this scenario over the optimal average inventory (which is associated with the optimal order quantity)? [Round your final number with three decimals, if needed]
