You decided to invest $10,000 that you won in a contest. You found three accounts to divide your money into. One account pays 5% interest, the other pays 7% interest and the last account pays 10%. You can only put half the amount in the 10% account than you put in the 5% account. At the end of the year you earned $670 in interest. How much did you invest in each account? Write your answer as an ordered triple in the correct order (amount in 5%, 7% and 10%)
