You are planning for retirement 35 years from now. You plan to invest $5,300 per year for the first 8 years, $6,800 per year for the next 9 years, and $13,600 per year for the following 18 years (assume all cash flows occur at the end of each year). If you believe you will earn an effective annual rate of return of 10.3%, what will your retirement investment be worth 35 years from now?
