Scenario 1-2a. Suppose there are three residents in a neighborhood, Isabelle, Joe, and Kennedy. They are considering the allocation of a certain public good in the neighborhood. Isabelle’s demand for the public good is Q = 80 – 4P. Joe’s demand for the public good is Q = 40 – 2P. Kennedy’s demand for the public good is Q=20-P. If your answer is not a whole number, please make sure to round to the nearest hundredth.Refer to Scenario 1-2a. What is the socially optimal number of the public good if the marginal cost of producing them is $25?
