Answer:
b. 26
Explanation:
Marginal utility refers to the utility gained by the consumption of an additional unit of a commodity. It is the satisfaction enjoyed by a consumer for the additional use of a unit of a good or service.
Given that the total marginal utilities is 105 and the marginal utilities of the first, second, and fourth sodas are 35, 28, and 16 respectively, the marginal utility of the third soda
= 105 - (35 + 28 + 16)
= 26
