A) 0
B) 1
C) 2
D) 3
E) 4
42) The marginal benefit of reducing pollution and the marginal cost of reducing pollution are given by the following equations: MB = -2 + 18, and MC = 2 + 2, where U is the number of units of pollution abatement.

D) 16
E) 18
43) Refer to Table 17-1. Suppose a public authority has the mandate to maximize social welfare by choosing the appropriate amount of pollution abatement. The optimal amount of pollution abatement is ________ units and implies a ________ amount of pollution remaining.

C) 5; positive
D) 70; positive
E) 5; negative
44) Refer to Table 17-1. Suppose a public authority has the mandate to maximize social welfare by choosing the appropriate amount of pollution abatement. The marginal cost of reducing pollution by one unit is ________ at a(n) ________ rate.

B) increasing; decreasing
C) increasing; increasing
D) decreasing; decreasing

D) $650
E) -$1150
50) Suppose a farm that is polluting an underground water supply faces the following marginal costs for abating units of pollution:
A) because abating the 4th unit adds more to social costs than to social benefits
B) because the total net benefit of abating the 4th unit is greater than the total cost
C) because the total cost of abating 4 units is greater than the total benefits
D) because it is not productively efficient
E) because the farmer has no way to charge a price for the units of pollution abated
