Flexibler Bank is offering a 30-year mortgage with an APR of 6%. With this mortgage your monthly payments would be $2000 per month. In addition, Oppenheimer Bank offers you the following deal: Instead of making the monthly payment of $2000 every month, you can make half the payment every two weeks (so that you will make 52 2 = 26 payments per year). How long will it take to pay off the mortgage if EAR of the loan is unchanged? What is the amount of the last payment?
