Final answer:
Before payment, the contract between Cadence and Domestic Auto Service is executory, as payment is still pending for the tire replacement service provided.
Step-by-step explanation:
The question concerns the status of a contract before a service has been paid for, which is in the realm of law, particularly contract law. In this scenario, Cadence had a tire replaced by Domestic Auto Service and has yet to pay for this service.
At this point, the contract between Cadence and Domestic Auto Service is executory, because both parties still have outstanding obligations to fulfill to complete the contract. Cadence needs to pay for the tire, while Domestic Auto Service has already provided the tire replacement service.
