The price of gasoline is $2.50 per gallon at the closest gas station, but is only $2.30 per gallon at a gas station two miles away. by driving to the farther gas station, the opportunity cost is: a) non-existent because gas is cheaper at the farther station. b) $0.20 per gallon, the difference in price between the two gas stations. c) the cost of filling one's tank at the original price of $2.50 per gallon. d) the value of one's time and expenses to go to the farther gas station.

D

Explanation:

The opportunity cost is the cost that someone have when they decide to do something and not doing another thing. In this case, if she or he decides to go to the farther gas station the opportunity cost is in terms of time, because he or she could spend those minutes (from the actual position to the gas station) doing something else (for example, eating). Cost are also in terms of gas because the gas that he or she spent to go to that gas station, could be used to drive somewhere else.

there are so many examples for that in different areas, like biology experiment carried out in our lab recently.
