Kathy Myers frequently purchases stocks and bonds, but she is uncertain how to determine the rate of return she is earning. For example, three years ago she paid $$21,000$ for $950$ shares of Malti Company$$s common stock. She received a cash dividend of $$770$ on the stock at the end of each year for three years. At the end of three years, she sold the stock for $$24,000.$ Kathy would like to earn a return of at least $9\%$ on all of her investments. She is not sure whether the Malti Company stock provides a $9\%$ return and would like some help with the necessary computations.
