According to the current one-year loan interest rate of 5.3 1%, 91300× 5.31%= 4848.03.

If the time limit in the supplementary question is less than half a year, the half-year loan interest rate is calculated as 4.86% for half a year (including half a year). Then 91300× 4.86% = 4437.18. Total principal and interest is 95737.438+08.
