Suppose there are three polluting sources with MAC₁ = 75

Question

Suppose there are three polluting sources with MAC₁ = 75 - 0.25E,MAC₂ = 120 - 4E and MAC₃ = 50 - 0.5E.When MAC equals $20,the aggregate level of abatement for these sources would be _______.

Quizplus · Accepted Answer

To determine the aggregate level of abatement, we need to find the value of E (emission level) for each polluting source when MAC= $20. For MAC₁ = 75 - 0.25E, substituting MAC=$20 gives: $20 = 75 - 0.25E 0.25E = 55 E = 220 For MAC₂ = 120 - 4E, substituting MAC=$20 gives: $20 = 120 - 4E 4E = 100 E = 25 For MAC₃ = 50 - 0.5E, substituting MAC=$20 gives: $20 = 50 - 0.5E 0.5E = 30 E = 60 Therefore, the aggregate level of abatement = (220-20) + (120-25) + (50-60) = 200+95-10 = 305 units. So, the answer is C.
