What term defines the total satisfaction derived from consuming all units of a good or service?

The term that defines the total satisfaction derived from consuming all units of a good or service is Total Utility. This concept is fundamental in economics as it describes the overall benefit or happiness a consumer receives from consuming a certain quantity of a good or service.

Total Utility is different from Marginal Utility, which refers to the additional satisfaction gained from consuming one more unit of a good or service. While Marginal Utility focuses on the incremental change in satisfaction, Total Utility encapsulates the complete satisfaction resulting from all units consumed, showing how consumption contributes to a consumer's overall well-being.

Economic Efficiency pertains to the optimal distribution of resources to maximize total output and satisfaction, while Diminishing Marginal Utility describes the principle that as a consumer consumes more units of a good, the additional satisfaction gained from each successive unit tends to decrease. Understanding these concepts helps in analyzing consumer behavior and decision-making in economics.
