Subtract the totals from each other and reach a solution. Economists use this measurement to estimate how much of a good or service customers want to buy. Calculate or determine the marginal utility of the first product or good. To find marginal utility, she finds the difference between both visits.

This law of diminishing marginal utility states that the marginal utility of income drops continuously as income rises. Utility is the satisfaction or benefit derived by consuming a product. Next, gather together all of the purchased items from the second (and any consecutive) events. Divide both differences and set them equal to marginal utility. In the context of cardinal utility, economists sometimes speak of a law of diminishing marginal utility, meaning that the first unit of consumption of a good or service yields more utility than the second and subsequent units, with a continuing reduction for greater amounts.

Use the marginal utility equation, which is MU(x) = dU/dx, where "x" is your variable. Note that utility isn't necessarily maximized when the MU starts to become negative. Sometimes, economists like to subdivide utility into individual units that they call utils. Let's also say that one fish costs $2. This occurs when having more than one of an item fails to bring further satisfaction to a customer. This occurrence became known as the paradox of value, which was later solved by marginal utility.
