Fifteen years ago, Hailey invested $4,000 and locked in an annual interest rate of 7 percent for 30 years (ending 15 years from now). Aidan can make a 15-year investment today and lock in an interest rate of 9 percent. How much money should he invest now in order to have the same amount of money in 15 years as Hailey? (Do not round intermediate calculations. Round your answer to 2 decimal places.)
