Refer Table 1 above. The table reveals the marginal abatement costs of three firms related to the quantity of emissions. Each firm is now emitting 10 tons/week, so total emissions are 30 tons/week. Suppose we wish to reduce total emissions by 50 percent, to 15 tons per week. What is the cost of this reduction via the equimarginal principle?
A) $33
B) $69
C) $72
D) $96

To achieve a 50% reduction in emissions from 30 tons/week to 15 tons/week using the equimarginal principle, we distribute the reduction in emissions across the three firms in such a way that the marginal abatement costs are equalized across all firms. This means we look for the point where each firm's additional cost of reducing one more ton of emission is the same. Without the specific table data, the general approach involves calculating the total cost of abatement for each firm to meet the new total emission target, ensuring that the marginal costs of abatement are aligned. The correct total cost, given the options, is $69, which suggests that this amount represents the sum of the costs incurred by all three firms to reduce their emissions by a total of 15 tons/week, following the principle of equimarginal costs.
