An investment of $180,000 was made by a business club. The investment was split into three parts and lasted for one year. The first part of the investment earned 8% interest, the second 6%, and the third 9%. Total interest from the investments was $8520. The interest from the first investment was 6 times the interest from the second. Find the amounts of the three parts of the investment.

  1. If the amounts invested are x,y,z then they have told us that

    x+y+z = 180000
    .08x + .06y + .09z = 8520
    .08x = 6 * .06y

    I suspect a typo, since even if the whole amount were invested at 6%, the interest would be 10,800. In other words, there's no way to solve these equations and get positive amounts.
