Quantitative business analysis:

Jan Yu purchased seven IBM $ 1,000 convertible bonds at $ 105. each bond was convertible  to 25 shares of IBM stock in 5 years. at the end of five years , IBM stock was selling at 97$, if Jan converted, hat would be her five-year capitol gain? Returning to the first problem assume that the stock price after five years was $ 38. how much more money would Jan get by cashing I the bonds rather than converting to stock?  

the city of Jamestown, Virginia, issued $ 27,000,000 worth of callable bonds at 9 % on January 1, 2008. the bonds were due in 2023. if interest rates were to fall from 6.5%  on January 1, 2015, how much could Jamestown save by reissuing the bonds at the 6.5% rate on January 1, 201?

Assume hat an investor had purchased $ 500,000 worth of the Jamestown bonds referred to in problem three. how much interest will he lose from having the bonds called if he reinvested in the new bond issue?
