Answer:
$42,000
Step-by-step explanation:
Calculation for the amount borrowed
Amount borrowed=$1,260/(12% x 3/12)
Amount borrowed=$1,260/0.03
Amount borrowed=$42,000
Note that October 1, 2016 to 31 December 2016 will gives us 3 months
Based on the above calculation $42,000 which is the amount borrowed x 12% x 3/12 = Interest expense amount of $1,260
Therefore the amount borrowed is $42,000
