The Equation for the Interest Rate of a Bond Is $$\mathrm { R } = \frac { \text { face value } - \text { initial price } } { \text { initial price } } \text {. }$$

The equation for the interest rate of a bond is

A) $$\mathrm { R } = \frac { \text { face value } - \text { initial price } } { \text { initial price } } \text {. }$$
B) $$\mathrm { R } = \frac { \text { face value } - \text { initial price } } { \text { face price } } \text {. }$$
C) $$\mathrm { R } = \frac { \text { face value } + \text { initial price } } { \text { initial price } } .$$
D) $$\mathrm { R } = \frac { \text { face value } + \text { initial price } } { \text { face price } } \text {. }$$
E) $$\mathrm { R } = \text { face value } - \text { initial price }$$
