Your uncle has $$333,000$ invested at $8\mathrm{.}50\%,$ and he now wants to retire. He wants to withdraw $$45,000$ at the end of each year, starting at the end of this year. He also wants to have $$25,000$ left to give you when he ceases to withdraw funds from the account. For how many years can he make the $$45,000$ withdrawals and still have $$25,000$ left in the end?
