II. The Troll Road Company is considering building a toll road. It estimates that its linear demand curve is as shown below. Assume that the fixed cost of the road is $0.5 million per year. Maintenance costs, which are the only other costs of the road, are also given in the table.

1. Using the midpoint convention, compute the profit-maximizing level of output.
2. Using the midpoint convention, what price will the company charge?
3. What is marginal revenue at the profit-maximizing output level? How does marginal revenue compare to price?

Answer 1

1. 0.9乘2 -1.2=0.6 或 0.8乘3-1.8=0.6
2. 0.9 or0.8
3.If the price is currently 0.9 ,the marginal revenue is 2.4-1.8=0.6 0.6 is smaller than the price 0.9
