Answer:
In this scenario, Carl, the salesperson from Acme Home Improvement Company, came to Steven's house and sold him replacement windows on credit, with Steven using his house as collateral. Since Steven made the decision to purchase the windows and agreed to the terms of the contract, he is generally bound by the agreement and is liable for fulfilling the contract. In this case, there is no indication that Steven has a right to cancel the contract or return the windows unless there are specific provisions within the contract itself or local consumer protection laws that provide such rights.
