Consider two consumers with the following demand functions for a public good:

P1=10- 1/10 G

P2= 20-1/10 G

Where pi is the price that i is willing to pay for a quantity G. a. What is the optimal level of the public good if the marginal cost of the public good is $25? b. Suppose that the marginal cost of the public good is $5. What is the optimal level? 2 c. Suppose that the marginal cost of the public good is $40. What is the optimal level? Should the consumers make an honest statement of their demand functions?
