4. Assume that a monopolist faces the following equations below for demand, marginal revenue, average cost and marginal cost (note that we're using AC instead of TC in this question). Demand: P = 500 - 0.5Q Marginal Revenue: MR = 500 - Q Average Cost: AC = 100 Marginal Cost: MC = 100 Now, assume that this firm chooses to engage in price discrimination, and considers setting 2 different prices. One price for Group 1, a group of consumers who prefer to buy this good on weekdays, and another price for Group 2, a group of consumers who prefer to buy this good on weekends. These prices are provided below . the weekday price for consumers in Group 1 is $250 . the weekend price for consumers in Group 2 is $150 Assume that consumers fit into one or the other of these two groups, based on their willingness to pay for widgets. Assume further that the firm can successfully engage in a pricing strategy of price discrimination. If the firm pursues this pricing strategy, answer the following: a. The profit earned from Group 1 (the group facing the $250 price) is equal to b. The profit earned from Group 2 (the group facing the $150 price) is equal to
