4. When he turned 35 years of age, Quentin realized that he needed to prepare for his retirement. He started by investing $1,000 at the end of the year. He continued saving $1,000 at the end of each year for a total of 10 years. He then doubled his savings to $2,000 per year for the following 10 years. Realizing that retirement was getting really close now, he doubled his savings again to $4,000 per year for an additional 10 years. How much money will Quentin have accumulated by the end ofthe 30th year? The average rate of return on his savings over the 30 years was 10% per year compounded annually. [Ans.: $253,640] (25 points) S. If Quentin (see problem 4 above) had started saving at age 25, rather than waiting until age 35, what uniform annual savings amount would he have needed to make to accumulate the same amount of money? Assume an average rate of return of 10% per year throughout the analysis period (15 points)
