1. Economies of scale Vision Source is a cable television provider. In the long run, Vision Source can provide cable television for 20,000 homes each month at a total cost o $700,000, cable television for 30,000 homes at a total cost of $750,000, or cable television for 40,000 homes at a total cost of $800,000. Use the purple points (diamond symbol) on this graph to plot points of the long-run average cost curve at outputs of 20,000, 30,000, and 40,000 homes. 50 Average cost 10 20 30 40 50 HOMES SERVED (Thousands) AVERAGE COST (Dollars per home per month) 20
