7. Problems and Applications Q7 The residents of the town Ectenia all love economics, and the mayor proposes building an economics museum. The museum has a fixed cost of $2,400,000 and no variable costs. There are 100,000 town residents, and each has the same demand for museum visits: QD = 11 – P, where P is the price of admission. On the following graph, use green points (triangle symbol) to graph the museum's average-total-cost curve at the following quantities: 1,000 visits, 2,000 visits, 3,000 visits, 4,000 visits, 6,000 visits, and 12,000 visits. Then use the orange line (square symbol) to graph the museum's marginal-cost curve.
