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.

LOL!

- anonymous

R U sure the next to last sentence is accurate?

- anonymous

hmmm lemme c

- anonymous

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

- anonymous

Yes it's right. @ Arman....what?!

- anonymous

This problem is a owletgit lolol

- anonymous

Yeah, I know it's tough~

- anonymous

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

lemme c

- anonymous

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

- anonymous

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

- anonymous

nope. that's what it says.....

- anonymous

do the first part is 21000?

- anonymous

*so

- 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

but the total was only like 3060.

- anonymous

Total is 40k

- anonymous

interest i mean

- anonymous

I see what I did wrong. Tommy another sec

- anonymous

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

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

- anonymous

the three*

- anonymous

is something wrong?

- anonymous

I don't know if that makes any sense to you. do you have the final answer anyway?

- anonymous

Lol, ok. lemme c.

- anonymous

Oh my gosh.........it's right!

- anonymous

A is 20193.66 b is 6731.28 c is 13025.06

- anonymous

Actually the 18,12, and 10 was right!

- anonymous

^^
I knew it was right :P .. I was just asking if it makes sense to you? lol

- anonymous

made*

- anonymous

I got a problem for kelly:
there is a integer, x, that is 10 digits long that if entered telephonically goes to you. What is x?

- anonymous

lol.. this is a hard one for her :P

- anonymous

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

- anonymous

anyway guys, it's my bed time already.. don't forget to click "become a fan", next to my name.. I hope you get the right answer arman!

- anonymous

come on!

- anonymous

I don't do "problems"!

- anonymous

...........obviously.......lol. sigh.

- anonymous

A telephone!

- anonymous

A telephone... that's no number! And think of it this way, you can ask me all the math problems you want ;)

- anonymous

lol...silly,

- anonymous

you know you blew that last one! ;)

- anonymous

Haha i think I'm a bit young anyways :P

- anonymous

That was a bs question though -.-

- anonymous

How is that?

- anonymous

Cause nobody would several need to do a problem like that -.- and you knew the answer

- anonymous

?

- anonymous

"?"?

- anonymous

Cause nobody would several need to do a problem like that -.- and you knew the answer

- anonymous

whats that mean?

- 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

I didn't know the answer. Trust me! That other guy knew it.

- anonymous

Subjugation whateverrrr its still trivially useless :P

- anonymous

Ahhhhhh* not Subjugation... stupid autospellcheck

- anonymous

No I have to go grab a dictionary!

- anonymous

Lol

- anonymous

to make submissive or subservient; enslave.....what the hell?

- anonymous

eh,

- anonymous

What I don't get is why do you have all these words problems?

- anonymous

math homework, duh!

- anonymous

Would you prefer I give you regular problems?

- anonymous

guess not...

- anonymous

Lol whatsup grade are you in? And id love to help but I think the others got you covered-i have to put my brain to my work, I can chat though

- anonymous

What... Damn spellcheck
