Question

Suppose that the total utility from consuming one unit of good X is 54 utils, the total utility of two units of good X is 74 utils, and the total utility of three units of good X is 84 utils. The marginal utility of the third unit is___________.
a. 10 utils.
b. 70.67 utils.
c. 12.25 utils.
d. 20 utils.

Answer 1

Answer: a. 10 utils

Explanation: The marginal utility from consumption of the third unit of goods is gotten by taking the difference between the total utility derived from three units of goods and the total utility derived from two units of goods.

Total utility from three units = 84 utils

Total utility from two units = 74 utils

84 - 74 = 10 utils which is the marginal utility of the third unit.
