Answer: Opportunity cost
Explanation:
Opportunity cost could be seen as forgoing an item or a plan for that which has better priority when they both have same or similar values or cost, and this would be based on individuals decision and not a fixed standard. An example would be buying a house over a car, the individual at this point may be tired of paying rent and decided to buy a house which at this point could be the same cost with the car but for the sake of opportunity cost he chooses the house over the car.
