Ms. Adams received a bonus check for $15,000. She decided to divide the money among three different investments. With some of the money, she purchased a municipal bond paying 5.6% simple interest. She invested twice the amount she paid for the municipal bond in a certificate of deposit paying 4.2% simple interest. Ms. Adams placed the balance of the money in a money market account paying 3.8% simple interest. If Ms. Adams' total interest for one year was $635, how much was placed in each account?
