121. Your aunt has $500,000 invested at 5.5%, and she now wants to retire. She wants to withdraw $45,000
at the beginning of each year, beginning immediately. When she makes her last withdrawal (at the
beginning of a year), she also wants to have enough left in the account so that you can make a final
withdrawal of $50,000 at the end of that year (her last withdrawal is at the beginning of the year, your
withdrawal is at the end of that same year). What is the maximum number of $45,000 withdrawals that
she can make and still have enough in the account so that you can make a $50,000 withdrawal at the
end of the year of her last withdrawal? (Hint: If your solution for N is not an integer, round down to
the nearest whole number.)

is built into the annuity? Disregard taxes.
