A manufacturer produces milling machines. The milling bed screws necessary for each machine are produced by an outside supplier at a cost of $25 each. 5 screws are needed each production day. The storage cost is 15%, while the cost to order is $25. Assume work occurs 240 days per year. If a 1.5% discount is given on orders of 500 or more, should the discount be taken? Explain why or why not. What is the POQ in Days between Orders at the non-discount rate? What is the POQ in EOQ Per Units Daily Demand at the discount rate
