Ann McCutcheon is hired as a consultant to a firm producing ball bearings. This firm sells in two distinct markets, each of which is completely sealed off from the other. The demand curve for the firm's output in the first market is P₁=160-8Q₁, where P₁ is the price of the product and Q₁ is the amount sold in the first market. The demand curve for the firm's output in the second market is P₂=80-2Q₂, where P₂ is the price of the product and Q₂ is the amount sold in the second market. The firm's marginal cost curve is 5+Q, where Q is the firm's entire output (destined for either market). Managers ask Ann McCutcheon to suggest a pricing policy.
