Final answer:
If Tasia sued Aden for breach of contract after accepting his offer to sell his laptop, she would likely win because a contract was formed when she accepted Aden's offer and provided consideration, even though Aden changed his mind afterward.
Step-by-step explanation:
The question relates to whether Tasia would win if she sued Aden for breach of contract after Aden offered to sell his laptop to Tasia for $400, which Tasia accepted, and then Aden changed his mind. In law, a contract is formed when there is an offer, acceptance, and consideration. In this case, Aden's offer and Tasia's acceptance created a mutual agreement. The consideration is the thing of value that is being exchanged, which in this case would be Tasia's $400 and Aden's HP laptop.
Consideration does not require the actual exchange to have taken place at the time of contracting; it only requires that the party agree to do so. Therefore, Tasia did provide consideration by agreeing to pay $400, just as Aden provided consideration by agreeing to sell his laptop for that amount. Once Tasia accepted the offer, a binding contract was presumably formed, and Aden cannot revoke his offer. However, if specific terms of the sale were not finalized or if Tasia was underage or lacked capacity, there could be reasons why the contract wouldn't be enforceable. Absent such issues, Tasia would most likely win the case based on Aden's breach of a validly formed contract.
