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.

R U sure the next to last sentence is accurate?
anonymous

hmmm lemme c

The interstate formula doesn't do anything, the interstate values are totals
anonymous
  • anonymous
Yes it's right. @ Arman....what?!
anonymous
  • anonymous
This problem is a owletgit lolol
anonymous
  • anonymous
Yeah, I know it's tough~

I think it is stated incorrectly. The next to last statement should be about the amounts. 3060 = .08(2x) + .06(x) + .09(40000 - 3x)
anonymous
  • anonymous
lemme c
anonymous
  • anonymous
306000 = 8(2x) + 6(x) + 9(40000 - 3x) 306000 = 16x + 6x + 360000 - 27x 306000 = -5x + 360000 5x = 54000 x = 10500
anonymous
  • anonymous
8% = $21000 6% = $10500 9% = $8500
anonymous
  • anonymous
nope. that's what it says.....
anonymous
  • anonymous
do the first part is 21000?
anonymous
  • anonymous
*so
anonymous
  • anonymous
A is 3889.83, b is 2593.22 and c is 33516.95... the values are not 100% precise because a endless rationale was involved
anonymous
  • anonymous
but the total was only like 3060.
anonymous
  • anonymous
Total is 40k

interest i mean

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; \[x+y+z=40,000 \rightarrow(1)\] \[0.08x+0.06y+0.09z=3060 \rightarrow(2)\] \[0.08x=2(0.06y) \rightarrow(3)\]
anonymous
  • anonymous
.......
anonymous
  • anonymous
solving three equations, we get that: first investment x=18,000 second investment y=12,000 third investment z=10,000
anonymous
  • anonymous
the three*
anonymous

is something wrong?
anonymous
  • anonymous
I don't know if that makes any sense to you. do you have the final answer anyway?
anonymous
  • anonymous
Lol, ok. lemme c.
anonymous
  • anonymous
Oh my gosh.........it's right!
anonymous
  • anonymous
A is 20193.66 b is 6731.28 c is 13025.06
anonymous
  • anonymous
Actually the 18,12, and 10 was right!
anonymous
  • anonymous
^^ I knew it was right :P .. I was just asking if it makes sense to you? lol

arman, if you told me earlie, I would have sent you the answer and let you post it.. ;)

Cause nobody would several need to do a problem like that -.- and you knew the answer
anonymous
  • anonymous
whats that mean?
anonymous
  • anonymous
Well you knew the answers lol and there is no real life problem where you know a total investment and interstate without knowing the values but you somehow know that one interstate is double the other? It's a useless trivia question... no offense :)
anonymous
  • anonymous
I didn't know the answer. Trust me! That other guy knew it.
anonymous
