Invest now or later? Twins Drew and Gavin are both age 22. Beginning at age 22, Drew invests $3,000 per year for ten years and then never contributes another penny. Gavin waits ten years and then invests $3,000 per year for the next 35 years. Assuming they both earn 8.38 percent, how much will each twin have at age 67 years?https://advisors.vanguard.com/iwe/pdf/FASINVMP.pdf
