A retаiler purchаses а given item frоm a supplier and then sells the prоduct tо its customers.  The following data are estimated for the item under consideration.  Take ALL intermediate computations to the FOURTH decimal place. Annual demand = 5000                                                 Holding cost = $4 / unit / year Working days per year = 200 days                               Order cost = $50 Average daily demand = 25 units                                 Average lead time = 6 days Standard deviation of daily demand = 3 units             Standard deviation of lead time = 1.5 days If the best order quantity was 500, and you didn’t carry any safety stock, the maximum inventory level would be...
