What is the best definition of marginal benefit and how does it impact decision-making in economics?

Marginal benefit refers to the additional satisfaction or utility gained from consuming one more unit of a good or service. In economics, decision-making is influenced by comparing the marginal benefit of consuming an additional unit with the marginal cost. If the marginal benefit exceeds the marginal cost, it is considered beneficial to consume more. This analysis helps individuals and businesses make rational choices to maximize their overall well-being or profits.
