Calculate the present value of bond B if the required rate of return is: (1) 9%, (2) 12%, and (3) 15%. c.

Why? a. (1) The value of bond A, if the required return is 9%, is $ (Round to the nearest cent.) + (2) The value of bond A, if the required return is 12%, is $ (Round to the nearest cent.) (3) The value of bond A, if the required return is 15% is $ (Round to the nearest cent.) b. (1) The value of bond B, if the required return is 9%, is $ (Round to the nearest cent.) (2) The value of bond B, if the required return is 12%, is $ (Round to the nearest cent.) (3) The value of bond B, if the required return is 15%, is $ (Round to the nearest cent.) c.
