Currently, the store places orders to the supplier, with a reorder point of 4,200 boxes. The order quantity to the supplier is fixed at 5,000 boxes. Replenishment lead time is 4 weeks, fixed order cost per order is $100, each box costs the retailer $10, and the inventory holding cost is 25% per year If the retailer wants to achieve a 99% service level (use the z-value with one decimal, as in Table 13.4 on page 400 of the textbook). what should be the safety stock value?
