Answer :
Answer:
Sunk cost
Explanation:
When somebody spends some amount of money, no matter what's the use for, if that won't be refunded or recovered later, then the money spent (on 1/2 of the sandwich) it's called Sunk cost.
The cost associated with the sandwich left on the plate is sunk cost
Sunk cost is a cost that has already been incurred and cannot be recovered.
Sunk cost should not be considered when making future economic decisions.
In this question, the cost of the sandwich which is $3.25 has already been incurred - Bob has paid for the sandwich. This amount Bob has paid for the sandwich cannot be recovered since he cannot get a refund on the sandwich.
In deciding if to continue eating the sandwich or not, Bob should not consider the sunk cost (the cost of the sandwich). Instead, other factors should be considered. For example, if Bob has reached the point of satiation, there is no need eating the rest of the sandwich.
