2. Consider a town with two people, Bill and Ted. Bill's demand for tennis courts is given by Q 30-5P and Ted's demand for tennis courts is given as Q = 12 - 2P. The marginal cost of providing tennis courts is constant at $3. a. Suppose the tennis courts are a private good. Derive the market demand curve (social marginal benefit curve) and find the equilibrium quantity. (30 - 5P) + (12 - 2P) = 3 42 - 7P = 3 -7P = -39 P = approximately 5.57 Insert P into Bill or Ted's equation: Bill: Q 30-5(5.57) = approximately 2.15 optimal quantity of tennis courts Ted: 12 - 2(5.57) .86 optimal quantity of tennis courts b.

2. Consider a town with two people, Bill and Ted. Bill's demand for tennis courts is given by Q
30 - 5P and Ted's demand for tennis courts is given as Q = 12-2P. The marginal cost of
providing tennis courts is constant at $3. a. Suppose the tennis courts are a private good.
Derive the market demand curve (social marginal benefit curve) and find the equilibrium
quantity. (30-5P) + (12-2P) = 3 427P = 3 -7P = - 39 P = approximately 5.57 Insert
P into Bill or Ted's equation: Bill: Q
approximately 2.15 optimal quantity of
tennis courts Ted: 12-2(5.57) = .86 optimal quantity of tennis courts b. Suppose the tennis
courts are a public good. Derive the social marginal benefit curve and find the optimal quantity
of the public good.
