Answer:
Unamortized discount is $43,700
Explanation:
Unamortized bond discount=original bond discount-amortization to date
original bond discount is $46,000
Amortization =interest  payable-interest expense
interest payable=$400,000*10%*6/12
                             =$20,000
Interest expense=$354,000*10%*6/12
                              =$17,700
amortization of discount=$20,000-$17,700
                                         =$2300
unamorized bond discount=$46000-$2300
                                             =$43,700
The unamorized bond discount at the end of the first six months is $43,700
