Answer :
Final answer:
Adam's marginal benefit of consuming the third scoop of ice cream is less than $4, which is why he chose to only eat two scoops.
Explanation:
Adam is a rational economic decision maker who has decided to only consume two scoops of ice cream even though the marginal cost of the third scoop is $4. If Adam is choosing not to consume the third scoop, it is reasonable to assume that the marginal benefit he perceives from consuming the third scoop is less than its marginal cost. Therefore, the correct statement is that Adam’s marginal benefit of consuming the 3rd scoop is less than $4. This is because a rational consumer will only purchase an additional unit of a product if the additional utility derived from it (marginal benefit) exceeds the cost of consuming (marginal cost) one more unit.
