Questino:
Appalachian Coal Mining believes that it can increase labor productivity and, therfore, net revenue by reducing air pollution in its mines. It estimates that the marginal cost function for reducing pollution by installing additional capital equipment is
MC = 40P
where P represents a reduction of one unit of pollution in the mines. It also feels that for every unit of pollution reduction the marginal increase in revenue (MR) is
MR = 1,000 - 10P
How much pollution reduction should Applachian Coal Mining undertake?
