Answer:
Dr cash $660,000
Cr bonds payable $660,000
Dr interest expense $ 39,600.00
Cr interest payable $39,600.00
Explanation:
The issue of the bonds at face value implies that cash proceeds equal the face value of $660,000 which is then debited to cash account and credited to bonds payable.
The interest due on the bonds on 31st December payable on 1st January 2021 =face value*coupon rate
face value is $660,000
coupon rate is 6%
interest=$660,000*6%=$39,600.00
