Using semiannual compounding, find the prices of the following bonds:

a. A 9.7%, 15-year bond priced to yield7.5%.

b. A 6.4%, 10-year bond priced to yield 8.6%.

c. A 11.3%, 20-year bond priced at 9.1%.

Repeat the problem using annual compounding. Then comment on the differences you found in the prices of the bonds.
