please make the answer clear ty

You are buying a house and will borrow $175,000 on a 25 -year fixed rate mortgage with monthly payments to finance the purchase. Your loan officer has offered you a mortgage with an APR of 4.10 percent. Alternatively, she tells you that you can "buy down" the interest rate to 3.80 percent if you pay points up front on the loan. A point on a loan is 1 percent (one percentage point) of the loan value. As you are evaulating the mortgage, you also realize that you believe that you will only live in the house for 7 years before selling the house and buying another house. This means that in 7 years, you will pay off the remaining balance of the original mortgage. What is the maximum number of points that you would be willing to pay? (Do not round intermediate calculations and round your answer to 3 decimal places, e.g., 32.164.)
