Erika and Kitty, who are twins, have aspirations to become millionaires. Each plans to make a $9, 500 annual contribution to her "early retirement fund", beginning a year from today. Erika plans to open an account with the Safety First Bond Fund, a mutual fund that invests in high-quality bonds whose investors have earned 5 percent per year in the past. Kitty will invest in the New Issue Bio-Tech Fund, which invests in small, newly issued bio-tech stocks and whose investors on average have earned 15 percent per year in the fund's relatively short history. If the two women's funds earn the same returns in the future as in the past, how much will each twin have in her account at the end of five years? How long will it take each twin to accumulate $1,000,000? How large would Erika's annual contributions need to be for her to become a millionaire in 20 years
