Quizplus · Accepted Answer

To find the total utility derived from consuming three pretzels, we add up the marginal utilities of each pretzel up to the third pretzel:
30 + 20 + 5 = 55
Therefore, the total utility derived from consuming three pretzels is 55 units.
The best choice is C, because it gives the correct answer.
