Answer:
Jacquie, because the class is primarily a service
Explanation:
All the contract laws in the United States are governed either by the Common law or by the UCC or the Uniform Commercial Code.
The Uniform Commercial Code governs all the contracts transactions in the form of securities and goods including tangible objects such as purchase of vehicles, etc.
Whereas the contracts transactions that includes intangibles assets, services, real estates, insurances, etc. are all govern by the Common law.
In the context, when Tory sues Jacquie for denying the refund Tory says that this contractual transaction should come under the Uniform Commercial Code while according to Jacquie this transaction should come under the common law because Jacquie is giving teaching classes to the students which is mainly a service. So contractual transaction under service is goverened by the Common law.
Hence the answer is ---
Jacquie, because the class is primarily a service
