Kathy Myers frequently purchases stocks and bonds, but she is uncertain how to determine the rate of return that she is earning. For example, three years ago she paid $20,000 for 300 shares of Malti Companys common stock. She received a $258 cash dividend on the stock at the end of each year for three years. At the end of three years, she sold the stock for $24,000. Kathy would like to earn a return of at least 15% on all of her investments. She is not sure whether the Malti Company stock provided a 15% return and would like some help with the necessary computations. (Ignore income taxes.) a. Determine the net present value. b. Did Kathy Myers earn 15% return on her investment?
