Monopolies do not last in the long-run

Suppose Factory A emits 15,000 units of "Yuck" monthly, Factory B emits 30,000 units, and Factory C emits 45,000 units. Also suppose A's cost of reducing the emission is $1 per unit, B's cost is $2 per unit, and C's cost is $3 per unit

If the EPA prohibits any factory from emitting more than 15,000 units of yuck per month, what would be the total cleanup cost? A) $15,000 B) $40,000 C) $45,000 D) $90,000 E) $120,000
