Final answer:
Keri can sue Jerry for a discharge of contract due to a breach of contract, as Jerry failed to deliver the actual 65 Shelby GT350 that was agreed upon in the sale, thereby not fulfilling his contractual obligations.
Step-by-step explanation:
The situation described involves a discharge of contract due to a breach of contract on the part of the seller, Jerry. When Keri bought Jerry's house, she expected to receive the rare 65 Shelby GT350 as part of the sale agreement.
However, upon finding only a Hot Wheels model of the car, Keri discovered that Jerry had not fulfilled his obligations as agreed upon in the contract. This failure to deliver the specific item that was a significant part of the contractual agreement constitutes a breach of contract, which provides Keri with grounds to sue Jerry for non-performance.
