Discuss the relationship between total utility and marginal utility, using a hypothetical schedule.

Total utility is the total sum of the utilities obtained by the consumer from different units of a commodity whereas Marginal utility is the addition made to total utility by having an additional unit of the commodity.

MU_N = TU_N —TU_N-1

We can see in the table that as the total utilities increase the marginal utility decreases but when it is at maximum MU is 0. When TU decreases Mu is negative.
