Table 16-3: The information in the table below shows the total demand for premium-channel digital cable TV subscriptions in a small urban market. Assume that each digital cable TV operator pays a fixed cost of $100,000 (per year) to provide premium digital channels in the market area and that the marginal cost of providing the premium channel service to a household is zero.
