A friend has asked you to help him figure out a statement he received from his broker. It seems that, at the start of last year, your friend paid \(\$ 900\) for a bond, and sold it at the end of the year for \(\$ 890\). During the year, he received a single coupon payment of \(\$ 110\). The statement claims that his return (not including commissions and taxes) is \(11.11 \%\) for the year. Is this claim correct?
