Include correctly labeled diagrams, if useful or required, in explaining your answers. A correctly labeled diagram must have all axes and curves clearly labeled and must show directional changes. If the question prompts you to "Calculate," you must show how you arrived at your final answer. Use the following graph to answer parts (a)-(e). Prices and costs are in dollars. 60 MC ATC Price, Cost 48 42 36 30 24 18 12 6 D 0 4 8 12 16 20 24 28 32 36 40 MR Quantity The graph above shows the demand (D) , marginal revenue (MR), marginal cost (MC), and average total cost (ATC') curves for one of many profit-maximizing firms operating in the short run in an industry in which there are no barriers to entry. Each firm sells a similar but not identical product.(a) Assume the rm produces 16 units. Will the rm's economic prot be positive, negative, or zero? Explain. (b) If the rm charges $36, should this rm increase its price, decrease its price, or keep the price at $36 in order to maximize its total revenue? Explain. (c) If the rm increases its price from $36 to $42, does the deadweight loss increase, decrease, or remain unchanged? Explain. (d) Assuming the rm produces a quantity greater than zero, identify the rm's prot-maximizing quantity and price, and explain how you determined each. (e) Calculate the total cost of producing the prot-maximizing quantity identied in part (c). Show your work
