Consider the market for rides at an amusement park. All consumers have roughly the same demand as depicted in the following graph, which also shows the marginal revenue (MR) curve and marginal cost (MC) curve for rides at this amusement park. In particular, the marginal cost to the amusement park of an additional ride is constant at exist0.80. The park uses a linear pricing strategy by selling rides to all entrants for the same price. Place the red point (cross symbol) at the profit-maximizing price and quantity. Dashed drop lines will automatically extend to both axes. Then, use the purple rectangle (diamond symbols) to shade the area representing profit at the profit-maximizing price and quantity. Now suppose the park decides to switch to a two-part pricing scheme by charging an admission fee but also lowering the cost of an individual ride. In this case, the profit-maximizing per-ride charge would be ____. Use the green triangle to shade the region representing consumer surplus given this pricing plan. To maximize profits, the admission fee should be set equal to ____.
