I need help in understanding how to present the following:

:confused: A coworker of yours was discussing her investments with a broker. Your coworker was confused because she had purchased a 10% bond but the broker kept repeating that it had a 9% yield to maturity. Explain the concept of yield to maturity

If a bond is purchased at 10% but had a 9% yield to maturity, what does that mean?

Because she had purchased a 10% bond but the broker kept repeating that it had a 9% yield to maturity

Because she had purchased a 10% bond but the broker kept repeating that it had a 9% yield to maturity

There is no reason to have the same question posted 4 times in a row.
