Answer: The marginal utility is 2
Explanation:
Utility is the satisfaction derived from the consumption of a particular commodity. Total utility is the total satisfaction derived from the consumption of a particular commodity. Marginal utility is the extra satisfaction that a consumer gets from consuming a product. Utility is measured in utils.
Marginal utility increases with an extra consumption of a good at first but later it begins to reduce as the extra good consumed doesn't really have give the consumer enough satisfaction anymore.
Regarding the question, eating 5 hotdogs gives 40 utils and eating 6 hotdogs gives 42 utils.
The marginal utility is the extra utils which will be 42-40 which gives 2 utils.
