Can you explain the concept of marginal utility and how it influences decision-making in economics?

Marginal utility is the additional satisfaction or benefit gained from consuming one more unit of a good or service. In economics, decision-making is influenced by marginal utility because individuals tend to allocate their resources towards goods or services that provide the highest marginal utility relative to their cost. This means that people will continue consuming a good or service until the marginal utility no longer outweighs the cost, helping them maximize their overall satisfaction or utility.
