to determine the regular payment amount, rounded to the nearest dollar.
The price of a home is $160,000. The bank requires a 15% down payment. The buyer is offered two mortgage options: 15-year fixed at 8% or 30-year at 8%. Calculate the amount of interest paid for each optain. How much does the buyer save in interest with the 15-year obtain?
