1. (25 pts) (Show your calculations.) (Keep 2 digits after decimal point in case of fractional results) Consider a product's inventory. The annual demand for this product is 6,000 units. The ordering cost is $50 per order. It costs $10 on average to carry a unit for a year. (This information applies in (1.1). (1.2). (1.3), and (1.4) below.) (1.1) (10 pts) Suppose that the current order quantity is 400 units per order. Answer the questions (1.1.a) (1.1.b), (1.1.c), (1.1.d), and (1.1.e) assuming the order quantity is Q=400 units per order (1.1.a) Calculate the average inventory. Your answer: (1.1.b) Calculate the total annual holding cost. Your answer: (1.1.c) Calculate the number of orders per year. Your answer: (1.1.d) Calculate the current total annual ordering cost. Your answer: (1.1.e) Calculate the total annual cost of inventory. Your answer: (1.2) (6 pts) Calculate the best ordering quantity (EOQ). Your answer: (1.3) (4 pts) Suppose you use the best order quantity EOQ as you have found in (1.2). Calculate the total annual cost of inventory associated with the EOQ. Your answer (1.4) (5 pts) If the lead time is four days and safety stock is set at 12 units, calculate the re-order point ROP, assuming 300 workdays in a year. Your
