You take out a 35-year mortgage loan for $634000. The annual interest rate of the loan that you pay is 3.4%, and you make monthly payments. In addition to the required monthly payment, you decide to add an extra $410 to your payment to pay the loan off early. After how many payments will the loan be paid off completely? (Note: the last payment you make may not be for the normal amount you would pay, but it still counts as a payment.)
