Answer:
a.$8,400
Explanation:
Amortization of bonds discount = (100000 - 98000)/5years Â
                           = 2000/5
                           = 400
Interest expenses = interst on face value + amortization of bond discount
               = (100000*8%) + 400 Â
               = $8400
Therefore, The bond interest expense for the year ended December 31, 2018, is $8400.
