[7 points] Calculate Julie's bi-weekly mortgage payment. b. [6 points] of her 1st payment to the bank, how much will go to pay interest on the mortgage and how much will go towards paying down the loan? C. [6 points) What will be the total interest paid over the 25 years? d. [6 points) The mortgage will come up for renewal in 5 years. How much will she owe at that time? e.
