8. Ten years ago, the Montagues purchased a house in Iowa for $150,000. They made an initial down payment of $30,000 and secured a mortgage with interest charged at the rate of 9% per year on the unpaid balance. (Interest computations are made at the end of each month.) Assume the loan is amortized over 30 years. 2 b a. What monthly payment will the Montagues be required to make? 465.55 . What will be their total interest payment (over the entire term of the loan)? c. What will be their equity, if the house has net current market value of $180,000? (Hint: First find the future value of their "annuity" after ten years then find the "compound interest" amount the lender would expect to have after ten years. Then you can figure out how much they still owe)
