Hamilton Company manufactures engines. Hamilton produces all the parts necessary for its engines except for one electronic component, which is purchased from two local suppliers: Traynor, Inc. and Bello Company. Both suppliers are reliable and rarely deliver late; however, Traynor sells the component for $10.00 per unit and Bello sells the same component for $8.95. Hamilton purchases 70 percent of its components from Bello, because of the lower price. The total annual demand is 75,000 units. I.
