Suppose you are a factory owner and are considering three different processes (called A, B, and C) to reduce polluting emissions.

Question 2 (6 points) Suppose you are a factory owner and are considering three different processes (called A, B, and C) to reduce polluting emissions. You are required by regulation to reduce monthly emissions by 100 units. The marginal cost of emissions reduction for each of the different processes are given below, where MCA refers to the marginal cost of process A, QA refers to the quantity of emissions reduction by process A, etc. Process A: MCA = 5 QA Process B: MCB = 15 QB Process C: MCC = 20 00a a. In order to achieve the required emission reduction at least cost, how much of the emissions reduction should be carried out by each process? Briefly explain your calculations. Note that to make your explanation easier, it may be helpful to number your equations. (2 marks) b. What is the total cost of reducing emissions by the required amount? Briefly explain your calculations. (2 marks) 0. What combination of processes would you use if the marginal cost is constant for each process. In particular, MCA = 5, M08 = 15, M00 = 20. What is the total cost of meeting the regulatory requirement in this case? (2 marks)
