Answer:
Sunk cost
Step-by-step explanation:
The sunk cost is the cost already incurred that will not be recovered in the future. Plus, it's also called past expenses.
This expense is not considered at the time when the decisions are taking and it should be neglected as it is not relevant at the time of the decision-making process
In the given scenario since the amount already spent for a movie ticket and for popcorn and we know that we cannot recover now so it would be termed as a sunk cost
