Hi sir, I have a very poor economic professor; I am having trouble with this question. I want to know how I can get the answer to this, calculate the marginal cost, and calculate an optimal choice. There are 60 questions I have to complete, but the textbook doesn't address the same concepts as the assignment itself.

Suppose the total benefit and total cost to society of various levels of pollution abatement are as follows:

Hi s.h_math (https://biology-forums.com/index.php?action=profile;u=1067569)

I'll try your best to help you. Firstly, let's look at the first table. The way you calculate the missing columns is demonstrated in the attachment. Although keep in mind, the numbers are different, but the process is the same if you repeat for your unique set of numbers.

I've also attached a sample answer with another unique table.

Let me know if that helps!
