Answer:
$563,867.79
Step-by-step explanation:
Notes annual payments = $220,776
Notes payable January 1, 2019 = $870,000
Interest for the year 2019 = $870,000*8.5% = $73,950
Principal payment for 2019 = $220,776 - $73,950 = $146,826
Notes payable at the end of year 2019 = $870,000 - $146,826 = $723,174
Interest for the year 2020 = $723,174 * 8.5% = $61,469.79
Principal payment for 2020 = $220,776 - $61,469.79 = $159,306.21
Notes payable at the end of year 2021 = $723,174 - $159,306.21 = $563,867.79
