Answer: If the commercial is TRUE that every additional bite of food tastes as good as the first, the marginal utility from consuming more of the advertised product must be CONSTANT. Option D.
Explanation:
Marginal utility is the additional satisfaction an individual gets, from consuming an additional unit of a product or service.
Therefore, in the scenario given above, if every additional bite of food tastes as good as the first, then the additional satisfaction is just as good as the preceding satisfaction. We can therefore say that the marginal utility gotten from consuming that product is constant.
