Refer to Table $10-1,$ which is based on bonds paying $10$ percent interest for $20$ years. Assume interest rates in the market $($yield to maturity$)$ decrease from $12$ to $10$ percent.

What is the bond price at $12$ percent?

What is the bond price at $10$ percent?

What would be your percentage return on the investment if you bought when rates were $12$ percent and sold when rates were $10$ percent?

Note: Do not round intermediate calculations. Input your answer as a percent rounded to $2$ decimal places.
