Answer:
The correct answer is C) A typical consumer will receive less satisfaction from consuming the fourth hamburger than the third per week
Explanation:
The law of diminishing marginal utility states that the more you consume of a specific good or service, the less satisfaction it provides to you. If applies for anything. You may like pizzas a lot, but if you eat one large pizza everyday in a week, you will probably grow tired of it by saturday. This last point refers precisely to the fact that the marginal utily might not only decrease, but also become zero or negative. If the marginal utility is negative, it means that the good or service not only no longer satisfies you, but also harms you or makes you feel bad.
