(15 points) Karen expects to receive a check for $80,000 in two years' time from her trust fund, at which point she intends to deposit the amount into her savings account. Her savings account pays 10% per year in interest. She will need $45,000 as a down payment for a house 9 years from now, and can spend the rest.

She wants to withdraw funds in equal nominal amounts at the beginning of each year, with the first withdrawal occurring four years from now, and the last occurring 8 years from now, a total of five withdrawals/payments. ANSWER: 4
