Answer:
If he decides to buy the Snickers bar, his opportunity cost is not to buy the bag of chips or the cookie.
Step-by-step explanation:
Opportunity costs are the costs of an economic choice expressed in terms of the best missed opportunity: it values the unrealized return of the best possible alternative compared to the final decision made.
When a person strives to satisfy his needs in times of scarcity, he has to make choices between different options. The choices made thus have an opportunity cost. The opportunity cost of a particular choice indicates what the decision-maker who made the choice has to give up when he decides to use his limited resources to implement the option he has chosen.
