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: $$\begin{array} { l l l l l r }
\text { Tons of smoke emitted per day } & 4 & 3 & 2 & 1 & 0 \
\text { Total abatement cost, firm A } & 0 & \$ 14 & \$ 30 & \$ 50 & \$ 75 \
\text { Total abatement cost, firm B } & 0 & \$ 20 & \$ 45 & \$ 80 & \$ 120 \
\text { Total abatement cost, firm C } & 0 & \$ 25 & \$ 60 & \$ 100 & \$ 150
\end{array}$$
Suppose the government requires the three firms to reduce pollution to 2 tons of smoke per day,for a total of 6 tons.This will result in a total cost of __________.

Quizplus · Accepted Answer

To find the total cost, we need to add up the cost for each firm at the 2 tons per day level of pollution.

For firm A, the cost is $30.
For firm B, the cost is $45.
For firm C, the cost is $60.

Therefore, the total cost is $30 + $45 + $60 = $135.

So, the best choice is D.
