Dunkin' Donuts joined many other service providers by centralizing manufacturing. Doughnut making in a geographic area is now done centrally for many stores, and the doughnuts are trucked to stores in the early morning. Imagnie the decision of the franchisee: Jelly-filled, sprinkle doughnuts cost $0.10 from the central facility, and sell for $0.60 each, and demand for the past 10 days has been 50, 38, 27, 45, 62, 44, 44, 29, 31, 39. Day-old doughnuts are thrown out (hopefully). How many should be ordered?
