If a person deposits $$5,000$ now at $8\%$ interest and plans to withdraw $$500$ per year every year starting one year from now, how long can the full withdrawals be made?

What is the minimum number of years a person must deposit $$400$ per year in order to have at least $$10,000$ on the date of the last deposit? Use an interest rate of $8\%$ and round off to the higher integer year.
