Your first-year roommate has a start-up and implores you to invest. They say theyll double your money by graduation. You have $5,000 burning a hole in your bank account, but had been considering the stock market as your 5-year investment plan (or shenanigans around the city). If your new roommate could double your money in 5 years, what interest rate would the stock market have to achieve to be equivalent, if we compounded quarterly?
