For Exercises 61-64, set up a system of linear equations to represent the scenario. Solve the system by using Gaussian elimination or Gauss-Jordan elimination. Sylvia invested a total of $ 40 , 000 . She invested part of the money in a certificate of deposit (CD) that earns 2 % simple interest per year. She invested in a stock that returns the equivalent of 8 % simple interest, and she invested in a bond fund that returns 5 % . She invested twice as much in the stock as she did in the CD, and earned a total of $ 2300 at the end of 1 yr . How much principal did she put in each investment?
