A home improvement company was negotiating with a homeowner to add two rooms to a home. The company agreed to take a second mortgage as long as the homeowner also included the rest of the property in the loan. The company and the homeowner agreed to a price, and the company provided the necessary disclosure form on Monday and the homeowner signed the agreement at noon the following day. Assuming that the week had five business days, until what time could the homeowner rescind the loan?
