Bill Long wants to set up a fund to pay for his daughter’s education. In order to pay her expenses, he will need $23,000 in 4 years, $24,300 in 5 years, $26,000 in 6 years, and $28,000 in 7 years. If he can put money into a fund that pays 6% interest, what lump-sum payment must he place in the fund today to meet his college funding goals?
