- A large urban hospital produces solid waste. The table below
shows the hospital’s marginal cost of reducing waste and the
marginal benefit to society of doing so.

of reducing solid waste.
b. What is the socially optimal amount of waste to abate?
c. What is the net benefit to society of abating the socially
optimal amount of waste?
