You are turning $22$ years old today. You intend to retire at age $60$ and you want to be able to receive a $30-$year, $$250,000$ beginning$-$of$-$year annuity with the first payment to be received on your sixtieth birthday. You would like to save enough money over the next $28$ years to achieve your objective; that is$,$ you want to accumulate the necessary funds by your fiftieth birthday. If you expect your investments to earn $8$ percent per year, what equal annual deposit must you make at the end of each of the next $28$ years? You should be able to write one formula that references the assumptions rather than building a timeline in Excel, i$.$e$.,$ you should not have more than one cell with the same dollar amount in it$.$
