You decide to take a 30-year mortgage of $140,000 offered by the Bank of Montreal. Instead of making the monthly payment of $889.48 every month, you can make half the payment every two weeks (so that you will make 52 + 2 = 26 payments a year). How long will it take to pay off the mortgage if the EAR on the loan is 6.75%? (Note: Be careful not to round any intermediate steps less than six decimal places.) The amount of time to pay off the loan is weeks. (Round to the nearest integer.)
