A monopolistically competitive rm faces the following demand schedule for its product. In addition, the rm has total xed costs equal to 20. If the rm produces its profit-maximizing level of output and there is a constant marginal cost of $7 per unit, which of the following is incorrect? O This firm produces 3 units to maximize its profit. O Firms will leave the market and prots for rms that remain in the market will rise. C) This firm charges a price of $22 to maximize its prot. 0 This firm should expect its demand curve to shift to the left. The following table presents the Demand Schedule and Prots for Smart Phones. Suppose the market for smart phones is a duopoly and the two firms in the market are Apple and Samsung. Both Apple and Samsung make exactly the same phones but with different names: iPhone and The Galaxy. Assume a constant marginal cost of $200 and no fixed costs.
