A contract is an agreement enforceable by law and there are two sources of contract law: common law of contracts and the Uniform Commercial Code (UCC).

1. Distinguish between common law and the UCC as to how a contract is formed and what the required elements are for creating a binding contract under each.
2. What makes an expressed, implied, and quasi-contract void, voidable and unenforceable and provide an example for each. Be sure to explain these terms.
