Expert's answer

Mary borrows $80,000 to buy her home. Beginning next month she will pay the lender $720 per month for the next 20 years.

To calculate ROR firstly we should calculate the monthly interest rate i = 720/80,000*100% = 0.9%.

The annual percentage rate, APR = 0.9%*12 = 10.8%.

So, ROR = APR = 10.8%.
