This is the beginning of my problem: Southlake Corporation issued $900,000 of 8% bonds on March 1, 20X1. The bonds pay interest on March 1 and September 1 and mature in 10 years.
The bonds are issued at 100.

I do not understand what it means by the bonds being issued at 100. If I had this information I could continue my work.

Thanks in advance!

The bonds being issued at 100 just means the bonds were issued at the stated price or the par value of the bonds.

Bonds can be issued at the stated price, below par or above par. Below par would be a number below 100 like 97, which means that a $100 bond was issued at $97. Above par would be a number above 100 like 102, which means that a $100 bond was issued at $102.

Thank you very much. I researched it more, and that is what I finally figured out.
