Answer:
$939,220
Explanation:
6400000 +12000000 = 18400000
we have to calculate the average interest on the general borrowing
= (10% of 6400000/ 18400000) + (11% of 12000000/18400000)
= 10% x 0.3478 + 11% x 0.65217
= 0.03478 + 0.0717
= 0.10648
= 10.65%
avoidable interest = (amount borrowed x percentage) + (expenditure-amount borrowed) x 10.65%
= 3200000*12% + (8,413,333-3200000)x10.65%
= 384000 + 555219.9
= $939,219.9
≈ $939,220
