Use the following information to answer questions 33-34. Suppose Firm A and Firm B each produce 10 units of pollution. The marginal abatement cost associated with pollution reduction are: MCA = 20 + 4QA for rm A, and MCB = 4+4QB for rm B where QA and Q3 are the quantities of pollution reduced by each rm. Society's benet from pollution reduction is: MB = 48 - QT where QT is the total reduction in pollution. For question 33, what is the socially optimal level of each rm's pollution reduction? 0 4 for Firm A, 8 for Firm B O 24 for Firm A, 24 for Firm B O 6 for Firm A, 6 for Firm B O 20 for Firm A, 4 for Firm B For question 34, how much total pollution is there at social optimum? O 6 units 0 8 units 0 10 units 0 2 units
