Avery and Caden have saved $27,000

 towards a down payment on a house. They want to keep some of the money in a bank account that pays 2.4%

 annual interest and the rest in a stock fund that pays 7.2%

 annual interest. How much should they put into each account so that they earn 6%

 interest per year?
