Step-by-step explanation:
the journal entry to record the sales of the bonds
Dr Cash 4,901,036
Dr Discount on bonds payable 98,964
Cr Bonds payable 5,000,000
Amortization of bond discount per year = $98,964 / 20 years = $4,948.20
Accumulated amortization for the first 3 years (2016, 2017, 2018) = $14,844.60
carrying value at the end of 2018 = $4,901,036 + $14,844.60 = $4,915,880.60
