Answer:
Is irrelevant in decision making
Step-by-step explanation:
Since the suck cost is the cost that no longer is recovered so it should not be a factor to consider when making a decision. For example, you have bought a cinema ticket for this evening, but it is heavily rainy so you may get sick if you go to the cinema. The fact that you have paid for this ticket should not consider whether to go or stay home since you can not get this amount of money no matter what happens.
