Answer:
a. Determine the selling price of the bonds.
we can use the approximate yield to maturity formula to determine the price of the bonds:
0.035 = {30 + [(1,000 - MV) / 5]} / [(1,000 + MV) / 2]
0.035 x [(1,000 + MV) / 2] = 30 + [(1,000 - MV) / 5]
0.035 x (500 + 0.5MV) = 30 + 200 - 0.2MV
17.5 + 0.0175MV = 230 - 0.2MV
0.2175MV = 212.5
MV = 212.5 / 0.2175 = $977
b. Prepare an amortization schedule for the full bond term.
I used an excel spreadsheet because there is not enough room here
c. Prepare journal entries on the following dates.
1. January 1, 2020, bond issuance.
Dr Cash 38,280
Dr Credit issuance cost 800
Dr Discount on bonds payable 920
  Cr Bonds payable 40,000
2. June 30, 2020, interest payment.
Dr Interest expense 1,368
Dr Debt issue expense 146
  Cr Cash 1,200
  Cr Discount on bonds payable 168
  Cr Credit issuance cost 146
[($40,000 - $920) x 3.5%] - $1,200 = $168
($168 / $920) x $800 = $146
3. December 31, 2020, interest payment.
Dr Interest expense 1,374
Dr Debt issue expense 151
  Cr Cash 1,200
  Cr Discount on bonds payable 174
  Cr Credit issuance cost 151
[($40,000 - $752) x 3.5%] - $1,200 = $174
($174 / $920) x $800 = $151
