1. A product has a demand of 95 units per day. The lead time for the product is 4 days. The cost to place an order is $87 and the cost of holding inventory is 15% of the cost of the product. The product costs $30 per unit. Assume there are 250 working days in a year. a. Calculate the economic order quantity for this product. b. Calculate the reorder point (ROP) for this product. That is the point (quantity) to reorder the product so as not to run out of product since the lead time is 4 days. c. Suppose a safety stock of 30 units is needed to protect against a surge in demand. What is the ROP with safety stock
