What is meant by the statement that "optimal decisions are made at the margin"?

What will be an ideal response?


In economics, the word "marginal" means "extra" or "additional." Economists reason that the optimal decision is to continue any activity up to the point where the marginal benefit equals the marginal cost, so optimal decisions are made at the point where the extra benefit received from an activity is equal to the extra cost associated with that activity.
