An electronics retailer sells laptops at a steady rate of 7,500 per quarter. It costs the manufacturer $350 tomake each laptop, and they charge $400/laptop to the retailer. The manufacturer produces the laptop at asteady rate that matches demand, and incurs a fixed cost of $2,800 to fulfill each retail order. Both theretailer and the manufacturer have an annual holding cost percentage of 20%. The retailer places 10orders with the laptop manufacturer each quarter (which it determined from an EOQ calculation). What quantity discount should the manufacturer offer the retailer in order to minimize the total supplychain costs?
