Answer :
Avoidable interest = $427,298.28
Explanation :
With the help of following steps we can calculate the avoidable interest on this project :
Interest payable on short term loan = $1,612,700 × 10% = $161,270
Interest payable on long term loan = $1,005,400 × 11% = $110,594
Therefore,
Weighted average interest rate = ($161,270 + $110,594) ÷ ($1,612,700 + $1,005,400) × 100
= 10.38%
Now
Avoidable interest is
= [$1,986,000 × 12%] + [($3,806,600 - $1,986,000) 10.38%]
= $427,298.28
