The graph illustrates an average total cost (ATC) curve (also sometimes called average cost), marginal cost (MC) curve, average variable cost (AVC) curve, and marginal revenue (MR) curve (which is also the market price) for a perfectly competitive firm that produces toy spaceships. Please answer the three questions, assuming that the firm is profit maximizing and does not shutdown in the shortrun. What is the firm's total revenue? What is the firm's total cost? What is the firm's profit? (Enter a negative number for a loss.)
