If a consumer is evaluating whether to purchase a third slice of pizza after enjoying two, which economic principle suggests that the satisfaction from the third slice will likely be less than from the first two?

When you eat a slice of pizza, the first slice gives you a lot of enjoyment, but each extra slice gives you a little less extra pleasure. This idea is called diminishing marginal utility, meaning the benefit you get from each additional slice gets smaller. So after the first two slices, the third slice will feel less satisfying because the extra pleasure is lower. For example, if the first slice makes you feel very full and happy, the third slice might only add a little more satisfaction, not as much as the first. This principle helps explain why people often stop buying more when the extra benefit drops.
