Explanation:

The bond issue brings a cash inflow of $340,000, an increase in cash which should debited to cash and credited to bonds payable account confirming that an amount of $340,000 is owed to the bondholders.

Assuming the market interest rate of 9% is the same as the coupon interest rate,the semi-annual interest is calculated thus:

9%*$340,000*6/12=$ 15,300.00  

The interest is for six months hence the need to prorate the interest.
