17000 loan is still 22000. Then the interest is 22000- 17000, which is equal to 5000 yuan. If the annual interest of a loan with the principal of 17000 yuan is 22000, it will be 22000+07000× 100. The answer is annualized rate 129.38+0438+076. If the interest is ten years, the annualized rate is 12.38+038+076.
