Explanation:
The opportunity cost of an economic decision can be defined as the cost of giving up the second-best alternative. A person received a five-dollar burger joint gift card that expires today.
The person has to choose between eating out at a burger joint or having a home-cooked meal. If the person eats a home-cooked meal, he has to give up the five-dollar worth gift card. Also, the ingredients that he used in the meal could have been used later for something else.
