Answer to Question 1

Marginal social cost equals marginal private cost plus marginal external cost. So the marginal social cost of the chemical is 100 + 20 = 120 per ton.

Answer to Question 2

The hardbound book version typically comes out before the paper bound version is made available. Consumers who have a higher ability and willingness to pay and an aversion to waiting will pay a higher amount of the hardbound version. Those who have a lower ability to pay and a willingness to wait will delay purchase of the book until the paperback version comes out.
