question 27

Multiple Choice

Suppose that there are three power-generating plants,all of which generate emissions.The table summarizes the cost of emission reduction for each firm given five different levels of pollution: $\begin{array}{lllllr}\text { Tons of smoke emitted per day } & 4 & 3 & 2 & 1 & 0 \\\text { Total abatement cost, firm A } & 0 & \$ 14 & \$ 30 & \$ 50 & \$ 75 \\\text { Total abatement cost, firm B } & 0 & \$ 20 & \$ 45 & \$ 80 & \$ 120 \\\text { Total abatement cost, firm C } & 0 & \$ 25 & \$ 60 & \$ 100 & \$ 150\end{array}$
The least costly way of lowering smoke emissions from 12 tons to 9 tons would be for

• A) each firm to reduce emissions by 1 ton,emitting 3 tons each.
• B) Firm A to emit 1 ton,and the other firms to emit 4 tons each.
• C) Firm A to emit 2 tons,Firm B to emit 4 tons and Firm C to emit 3 tons.
