Ok.....here is another..arman, where ya at? lol :) An investment of 40,000 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 3060. The interest from the first investment was 2 times the interest from the second. Find the amounts of the three parts of the investment.

    The interstate formula doesn't do anything, the interstate values are totals

    I think it is stated incorrectly. The next to last statement should be about the amounts. 3060 = .08(2x) + .06(x) + .09(40000 - 3x)

    306000 = 8(2x) + 6(x) + 9(40000 - 3x) 306000 = 16x + 6x + 360000 - 27x 306000 = -5x + 360000 5x = 54000 x = 10500

    8% = $21000 6% = $10500 9% = $8500

    let x, y and z be the 1st, 2nd and the 3rd investments respectively. according to the given informations, we have the following three equations; \[x+y+z=40,000 \rightarrow(1)\] \[0.08x+0.06y+0.09z=3060 \rightarrow(2)\] \[0.08x=2(0.06y) \rightarrow(3)\]

    solving three equations, we get that: first investment x=18,000 second investment y=12,000 third investment z=10,000
