1. At age 25, James, thinking ahead, deposits $2500 into a retirement account with an average annual interest rate of 11%. Find James age when his investment is worth ten times its original value.
2. If James had funded this account at age 18, how much money would give the same results as depositing $2500 at age 25? Round your answer to the nearest dollar.
3. Suppose the $2500 James deposited when he was 25 has grown to $25,000 when he is 40. What was the average annual return on investment? Round your answer to the nearest tenth of a percent.
