Suppose that Media Cable is a single-price monopolist in the market for cable in Anywhere, Iowa. Media has five potential customers: Morgan, Larry, Clyda, Janet, and Tom.

Each of these customers are willing to purchase cable service, but only if the price is just equal to, or lower than, his or her willingness to pay. Morgan’s willingness to pay is $130; Larry’s, $100; Clyda’s, $80; Janet’s, $40; and Tom’s, $0.

Media Cable’s marginal cost per cable package is $40. The demand schedule for cable service packages is shown in the accompanying table.
