BYOB is a monopolist in beer production and distribution in the imaginary economy of Hopsville. Suppose that BYOB cannot price discriminate; that is, it sells its beer at the same price per can to all customers. The following graph shows the marginal cost (MC), marginal revenue (MR), average total
cost (ATC), and demand (D) for beer in this market.
Place the black point (plus symbol) on the graph to indicate the profit-maximizing price and quantity for BYOB. IF BYOB is making a profit, use the
green rectangle (triangle symbols) to shade in the area representing its profit. On the other hand, if BYOB is suffering a loss, use the purple rectangle
(diamond symbols) to shade in the area representing its loss.
