Final answer:
The case of Mr. Lopez and Paul's Famous Plumbing is an example of Uniform Commercial Code (UCC) as it pertains to the sale of goods (P-Trap pipe) in addition to the provision of services (repair work).
Step-by-step explanation:
This scenario with Mr. Lopez's kitchen sink flooding and Paul's Famous Plumbing offering a service and a separate charge for a P-Trap pipe is an example of the Uniform Commercial Code (UCC), specifically relating to sales of goods and services. The UCC governs commercial transactions in the United States and would apply here because the plumber is offering to sell a good (the pipe) in addition to providing a service (the repair work). This sets up a transaction where the cost of the service is separate from the cost of the goods, aligning with the principles set out in the UCC. Paul offers two options to Mr. Lopez: one where Paul supplies the pipe for an additional cost, and another where Mr. Lopez can procure the pipe himself; both are valid under UCC terms.
