If your required rate of return is 9 percent, what is the value of the bond?

This formula can calculate the value of a bond.
Value = present value (of bond) = face value/(1+r).
where r represents the return rate required, and n indicates the number period (in this instance, 9%)
If the face value is $1,000, and the rate of return required is 9% then the value of this bond would be as follows:
1,000/ (1+.09),9= 743.8164
