Answer:
B) The value of the ingredients that go into the home-cooked meal and the value of a five-dollar dinner at Burger Joint .
Explanation:
Opportunity costs can be defined as the cost for choosing one alternative investment or action over another.
If you choose to use the five dollar gift card, you are going to eat for free, although you might not enjoy that meal as much as your delicious home made dinner.
But if you choose to eat a delicious meal at home, you are going to lose the five dollars of the give card and will have to spend a certain amount of money in making the dinner. Those same ingredients could be used to prepare dinner tomorrow. That is your opportunity cost of eating at home.
