Scenario: Frank and Nancy Live in a Small Community on Cape

Scenario: Frank and Nancy live in a small community on Cape Cod in Massachusetts. For simplicity, assume Frank and Nancy are the only individuals in the community. Each has a demand for mosquito control, given by the following table, equations, and figure. Assume that mosquito control is a public good. Mosquito control is provided at a constant marginal cost of $120.

Frank's demand: qFᵣₐnk = 200 - p,
Frank's inverse demand = (Marginal Private Benefit) : p = 200 - q,
Nancy's demand: qNₐncᵧ = 100 - p,
Nancy's inverse demand = (Marginal Private Benefit) : p = 100 - q,

-Refer to the scenario above.In the private market equilibrium,what are the quantities demanded of mosquito control for Frank and Nancy? Explain your answer.

A) 0 units for Frank, 0 units for Nancy
B) 80 units for Frank, 0 units for Nancy
C) 80 units for Frank, 10 unit for Nancy
D) 120 unit for Frank, 20 unit for Nancy
