Suppose you plan to retire in 40 years. If you make 10 annual investments of $ 1,000 into your retirement account for the first 10 years, and no more contributions to the account for the remaining 30 years. If the retirement account earns a fixed 6% annual interest, how much will you have at your retirement? Round it to two decimal places without the $ sign, e.g., 1234567.89.
