Answer:
Sunk cost fallacy
Step-by-step explanation:
Sunk cost is mostly related to the sunk cost fallacy. This happens when a person or company refuses to change a decision simply due to the fact that they have already put the money down for it even though continuing with such is not the best decision. Such a fallacy has the ability of affecting even the smallest financial decision.
Here people believe they can recover money which they have spent and this is not actually true as sunk costs are not recoverable.
