On her 18^th birthday, Riley deposits $9,000 per year into a retirement account with an estimated 9.5% rate of return. She will stop making deposits after her 61^st birthday (i.e., she will make her final deposit on her 61^st birthday), and her investment will continue to grow until she retires at age 75. Assuming her deposits occur at the beginning of each year, how much money will Riley have in her retirement account on her 75^th birthday?
