Question 21 Not yet answered Marked out of 10.00 P Flag question Suppose that the Total Social Benefit associated with drinking water quality is estimated to be TSB = 300A - A?, where A is the percentage of mercury abated from drinking water and TSB is measured in millions of dollars. And the government's marginal cost of enforcement equals 140 and MACMKT = 60+3A. Find the marginal social cost (MSC) of abatement function and then find marginal social benefit (MSB) function associated with a federal policy that increases mercury abatement to 20 percent. Is 20% of abatement efficient? Solve for the efficient level of abatement. Explain
