You plan to put away $300 a month for the next 20 years. If you get a 2% interest rate for the first 10 years and then a 3% interest rate for the next ten years ( both compounded monthly), how much money do you have after 20 years? Carefully explain your reasoning. (Hint: think about this as putting in $300 a month for 10 years at 2%. Then separately consider the $300 a month for the second ten years at 3%. And add those.)
