Suppose xyz corp emits so2 in its production process. the plant manager estimates that the firm’s total abatement cost is 3a^2 + 2a, where a = tons of so2 pollution abated. as such, the firm’s marginal abatement cost is 6a + 2. the firm is currently emitting 8 tons of pollution. an emission charge of $26/ton of so2 emitted is instituted. a. if the firm chooses not to abate any of its baseline level of emissions, what is the firm's total pollution charge? b. if the firm chooses to minimize its pollution cost, how many tons of pollution will they abate? what is the abatement cost? what is the total pollution charge? how much can the firm save by using this approach? c. draw a detailed, labeled graph illustrating your responses.
