The application of the rule of marginal utility in real-world situations:

When you receive more of something you desire, such an item or service, you feel an additional sense of satisfaction known as marginal utility.

In reality, marginal utility holds true for the majority of human needs and desires. Marginal utility is the additional satisfaction you experience from purchasing more pizza, for example, if you go to buy some and discover that you can afford more than you anticipated.

The issue with marginal utility, though, is that if you continue to receive more of anything, you will reach a point when you no longer feel as satisfied as you did while receiving additional.

For instance, if you keep ordering more pizza on the same day, ultimately you will feel as though you have had enough and you won't want any more pizza. The Law of Diminishing Marginal Utilities is what's responsible for this situation.
