Answer to Question 1

B

Answer to Question 2

a) The community's marginal social benefit is the sum of Jake's marginal benefit and Elwood's marginal benefit. So the marginal social benefit from the 4th police car is 15 + 8 = 23.
b) The number of cars on duty is efficient if the community's marginal social benefit equals the marginal social cost. The marginal social benefit is the sum of Jake's marginal benefit and Elwood's marginal benefit. When three cars are on duty, the marginal social benefit is 25 + 12 = 37, which is the same as the marginal social cost. So the efficient number of cars is 3.
c) As before, the number of cars on duty is efficient if the marginal social benefit equals the marginal social cost. And also as before, the marginal social benefit is the sum of Jake's marginal benefit and Elwood's marginal benefit. But in this case, because for any number of police cars on duty marginal social cost exceeds marginal social benefit, the efficient number
