Tracy Chapman is saving to buy a house in five years. She plans to put 20 percent down at that time, and she believes that she will need $28,000 for the down payment. If Tracy can invest in a fund that pays 9.20 percent annually, how much will she have to invest today? (If you solve this problem with algebra round intermediate calculations to 6 decimal places, in all cases round your final answer to the nearest penny.)
