I have to solve this problem and I am stuck on solving the interest. Can someone possibly help me? I have the January 1 date all set, and I know the cash amount is $20,000 for the June 30 and December 31 dates. I just can't figure the interest out... Help?!

On January 1, 20x5, Becky Bishop Fashion Company issued ten-year, 8 percent bonds with a face value of $500,000. The semiannual interest dates are June 30 and December 31. The bonds were issued for $437,740 to yield an effective annual rate of 10 percent. The accounting year ends on December 31. Prepare entries in journal form without explanations to record the bond issue on January 1, 20x5, and the payments of interest and amortization of discount on June 30 and December 31, 20x5. Use the effective interest method of amortization. Round answers to the nearest dollar.
