Bond current yield: An investor must choose between two bonds:

$-$ Bond A pays $$80$ annual interest and has a market value of $$800.$ It has $10$ years to maturity.

$-$ Bond B pays $$85$ annual interest and has a market value of $$900.$ It has two years to maturity.

a$.$ Compute the current yield on both bonds.

b$.$ Which bond should he select based on your answer to part a$?$

c$.$ A drawback of current yield is that it does not consider the total life of the bond. For example, the approximate yield to maturity on Bond A is $11\mathrm{.}36$ percent. What is the approximate yield to maturity on Bond B$?$

d$.$ Has your answer changed between parts b and c of this question in terms of which bond to select?
