Suppose in a city, there are three types of individuals and each type has a different demand for public goods. The marginal benefit for A is MB=60-Q, marginal benefit for B is MB=90-Q, and marginal benefit for C is MB=85-Q. Suppose all of them have to pay the same the same price of $40. Suppose a limit of 40 is set on public good provision, Calculate the welfare change for individual C compared to the median voter outcome O a. -37.5 O b. 37.5 Ofc. 12.5 O:d. -12.5 Suppose in a city, there are three types of individuals and each type has a different demand for public goods.
