Fame Company manufactures engines. Fame produces all the parts necessary for its engines, except for one electronic component, which is purchased from two local suppliers: Hydra International and Parable Company. Both suppliers are reliable and rarely deliver late. Hydra sells the component for $12.00 per unit, while Parable sells the same component for $10.00. Fame purchases 80% of its components from Parable because of the lower price it offers. The total annual demand is 95,000 units.
