Answer:
10.66%
Explanation:
The computation of the weighted-average interest rate is shown below:
Particulars                     Principal           Interest
10%, 5-year note payable        $2,013,900         $201,390
11%, 4-year note payable         $3,826,400         $420,904
Total amount                  $5,840,300         $622,294
So, the weighted-average interest rate would be
= $622,294 ÷  $5,840,300
= 10.66%
