Hi. An explanation of your question is typed below. Take your time to read and understand it. I will make it as simple as possible.
Step-by-step explanation:
Opportunity cost can be defined as the cost of an alternative forgone when choice is made. This can be simply defined as the cost of something that is left undone as when a choice is made between 2 things to do.
An example is having to choose between going for a vacation or buy a PS5. When yo decide to go for the vacation, the opportunity cost is the PS5. That means you would rather go on a vacation that get a PS5. This can be due to a number of reasons but more often than not, money is usually the factor for making decisions.
That is the money you have at hand decides what you do with it. If you feel you vacation will not be as expensive as getting a PS5, this makes getting the PS5 delayed till the vacation is out of the way.
Other determinants of decision making thta transcends/goes beyond money includes; energy loss, time loss, etc.
These factors alongside money help to determine the opportunity cost.
I trust that you have an idea now about opportunity cost and how decision makers affects it. Cheers.
