Tim's Tires sells tires under the firm's own brand name and private label tires to discount stores. The tires sold in both sub- markets are identical, and the marginal cost is constant at $15 per tire for both types. The firm has estimated the following demand curves for each of the markets: PB = = 70 -0.0005QB (brand name) Pp = 20 -0.0002Qp (private label). Quantities are measured in thousands per month and price refers to the wholesale price. By selling the brand name and private label tires at different prices, the firm is using discrimination. With price discrimination, the optimal price of brand name tires is ✓. The optimal price of private label tires is ✓. The firm's TOTAL profit is ✓to prices. ✓price ✓and the optimal quantity is ✓and the optimal quantity is ✓ (assume fixed costs are zero). If the firm cannot price discriminate and must charge a single price in the market, the optimal price is and the optimal quantity is ✓. The firm's total profit in this case is approximately…

Suppose Ring Dental is the single supplier at HRM region provide the dental service and has a market demand curve Q = 40 – P; A total cost curve given by the formula: T C = 80 - 20Q + 2Q2 Find the profit-maximizing quantity, price, and profit. Now, suppose Halifax Dental wishes to separate the market and target to two different groups of customers young and old customers, the average cost = marginal cost = 10 for both markets Young customers with elasticity = -5 and DA = 12000 - 65P Old customers with elasticity = -7 and DB = 12000 - 55P What is the profit if Halifax Dental sets the equal price for both markets? (use the average elasticity for equal price) What is the profit if Halifax Dental charges different prices for each market?
