Based on the following data, calculate the safety stock quantities and the inventory cost associated with safety stock (based on the item unit cost) for the inventory items at four different service levels (50%, 80%, 90%, and 95%). Develop a table to present the inventory quantities and the safety stock costs at each service level. (Note: All items are independent demand items.)
