Step-by-step explanation:
The bonds will be issued at par as the coupon rate on bonds is equal to the market interest rate. Thus, cash will be received equal to the par value of bonds and the bonds payable will be credited.
The bonds make semi annual coupon payment. The semi annual coupon payment = 420000 * 0.06 * 6/12 = $12600
The interest/coupon will be recorded as an expense and the as it it paid on the same day, cash will be credited.
