Answer:
$322,400
Explanation:
Calculation for At June 30, 2021, Noble's unamortized bond discount
First step is to calculate unamortized bond for 2019-2020
Unamortized bond 2019-2020= $9,560,000 + [($9,560,000 × .1) - ($10,000,000 × .09)]
Unamortized bond 2019-2020=$9,560,000 + [($9,560,000 - $900,000)]
Unamortized bond 2019-2020=$9,560,000 + $56,000
Unamortized bond 2019-2020= $9,616,000
Second step is to calculate Unamortized bond for 2020-2021
Unamortized bond 2020-2021= $9,616,000+ [( × $9,616,000.1) - ($10,000,000 × .09)]
Unamortized bond 2020-2021=$9,616,000 + ($961,600 - $900,000)
Unamortized bond 2020-2021 = $9,677,600
Now let calculate unamortized bond discount
Unamortized bond discount =$10,000,000 - $9,677,600
Unamortized bond discount = $322,400
Therefore At June 30, 2021, Noble's unamortized bond discount should be $322,400
