Answer:
Edward's promise is not enforceable. Â Tony had already performed the act. Â He did not perform based on Edward's promise. Â He performed because of their fraternal brotherhood.
Explanation:
This situation looks like a unilateral contract whereby Edward makes a promise to Tony to pay him $100. Â However, we observe that Tony did not perform his actions in consideration of this reward. Â He performed because they were fraternity brothers. Â Therefore, Tony cannot enforce Edward's promise in any court. Â It is only left for Edward to fulfill his promise as a gentleman, not because he is legally obliged to.
