In preparation for retirement you plan to invest 14% of your annual salary into a mutual fund which guarantees a fixed annual rate of 6.2% compounded continuously. You currently make $30,000 a year and your salary will likely increase 4% each year. How much more money do you have in the mutual fund if you continue investing into the mutual fund for 40 years as opposed to 30 years?
You may not need to use calculus here but that is the method they are looking for. If anyone can solve it using definite integrals that would be great!
