You have a very good salary and a smart investment manager. She tells you that in only 6 years you can accumulate $688,530 from quarterly deposits of $20,000 into an account that has a historical return of 12% per year compounded quarterly. It seems like a “stiff” commitment, but one worth trying as you prepare for an early retirement from your current defense contractor engineering job. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. You are a cautious investor. Suppose the market does not perform as your investment manager predicts and the return is only 54% of what she predicted. What is the future value of your quarterly deposits?
