On the way home from the hospital after having minor outpatient surgery, Georgia Jones, stopped at an upscale electronics store. She was still groggy from both the anesthesia and powerful pain medication given to her during the procedure.

While in the store, Ms. Jonesnegotiates with a salesperson for the purchase and sale of an in-home entertainment system. Ms. Jones mentions the surgery to the salesperson, but the salesperson does not take note of Ms. Jones condition. The system that Ms. Jones ultimately decided upon is a top-of-the-line entertainment system with state-of-the-art viewing features and surround sound, at a cost of $18,000.00. With a personal check, Ms. Jones pays the salesperson 50% of the cost, with the remainder to be paid following installation. The transaction is reflected in appropriate contract documents and invoices and complies with all federal, state, and local regulations regarding the sale. All documentation is signed by both parties. The next day, Ms. Jones receives a call from the store to schedule the installation. Unfortunately, Ms. Jones does not really remember purchasing the entertainment system. Upon reviewing the transaction documents found on her kitchen table, Ms. Jones determines she is unable to afford such an expense and desires to cancel the contract. The contract itself has no cancellation provision. Is this contract valid, void, or voidable? Fully explain your answer, defining all legal terms.
