Marginal utility declining as more of a good is consumed means that total utility:
AStays exactly flat
BBecomes negative at once
CRises more slowly
DFalls immediately
Answer & Solution
Correct answer: C. Rises more slowly
1. Marginal utility is the addition each new unit makes to the total.
2. As a person receives more of a good, the additional utility from each additional unit of the good declines.
3. Each unit still adds something, so the total keeps rising.
4. It simply rises by smaller and smaller amounts.
