Total utility derived from consuming a commodity is correctly expressed as the:
Ahighest marginal utility among the units
Bsum of marginal utilities of the units consumed
Cproduct of marginal utilities of the units
Daverage of marginal utilities of the units
Answer & Solution
Correct answer: B. sum of marginal utilities of the units consumed
1. Total utility is defined as $TU = MU_1 + MU_2 + \dots + MU_n$.
2. It is therefore the sum of the marginal utilities of the successive units.
3. It is neither a product, an average, nor the single highest value, so those options are wrong.
