Can Olivia Enforce Samuel's Promise of $40,000?

Explanation:

No, Olivia cannot enforce Samuel's promise for $40,000. In contract law, for a promise to be enforceable, there must be a valid contract, which typically requires an offer, acceptance, consideration, and an intention to create legal relations. In this case, Samuel argues that there was no valid contract because there was no bargaining or consideration, and he also revokes the promise. Based on these arguments, Olivia would not be able to enforce the promise.
