I'm having a hard time figuring out the following.... I don't even know where to start.

Bobby will get annual returns of 13.0%, -8.0%, -9.5%, 5.0%, and 7.4% in the next five years on her investment in My Town, Inc. stock, which she purchases for $42,000 today. (Assume NO dividends during the 5 years and all annual returns are associated with the stock price/value).
