Question

Brayden is investing $1,617 in three different stocks: Zycodec, Unix, and Xenon. He will invest 40% of the total between Zycodec and Xenon in the Unix stock. Twice as much as the investment in Zycodec will be given to Xenon. How much will Brayden invest in the Unix stock?

Answer 1

I broke the question down but i just don't understand how to even begin calculating it! someone help please

Answer 2

This isn't a question about STOCKS. It's a brain dead algebra question

Answer 3

That isn't what i asked...

Answer 4

Someone HELPFUL please respond

Answer 5

its lil confusing for me..

Answer 6

I know right! i'll break it down, maybe you will know how to calculate it.
He has 1,617 $ to spend
there are 3 stocks
I have to find the toltal amount he invested in Zycodec & xenon because whatever the total of those two are, he invest 40% of the total on the Unix

Answer 7

so , x + y + +z = 1617..

40 % ( x + y ) = z

x + y = 100 * z / 40

so (100 * z)/ 40 + z = 1617

140 z = 1617 * 40

so z= 462 $..

this can be possibility..

Answer 8

I got $385 for z....

Answer 9

@stephstar101 : can u plz show steps ?

Answer 10

Stephstar101, that is one of my answer choices. But how did you calculate it?

Answer 11

it's not the answer, because it was the amount for Zycodec, Unix stock should be $462, is that one answer?

Answer 12

Yes that is one of the answer choices too

Answer 13

Okay I'll explain in a sec

Answer 14

Okay, thank you!

Answer 15

So you need to start with 3 different equations based off of what the question asks. The variables assigned correlate with the company name.

Equation 1: Z+U+X=1617 <- from the first sentence, he'll invest this much total in 3 stocks
Equation 2: .40(Z+X)=U <- comes from sentence 2, 40% of the sum of Z+X will equal U
Equation 3: 2Z=X <-2 times Z is the amount given to X

Let's start with the math!
.40(Z+2Z)=U <- replace the X from equation 2 with the X amount from equation 3
.40(3Z)=U <- add the Zs
1.2Z=U <- multiply .40 and 3 to get 1.2

Z+1.2Z+2Z=1617 <- plug in equation 3 and the 1.2Z you just solved for into equation 1
4.2Z=1617 <-add Zs together
Z=$385 <- divide 1617 by 4.2 to get the amount for company Zycodec

Plug it into .40(3Z)=U from a previous step.
.40(3*385)=U
U=$462, and that's your answer!

Answer 16

@stephstar101 : so 462 is right answer ??

Answer 17

Pretty much, since Unix is U, and that's what it's looking for.

Answer 18

That is a long equation But thank you for explaining... I'm copying it down for my notes!

Answer 19

Yeah, there are 3 equations too many >.< But I hope it helped a little going through ALL the steps. Probably the hardest part is understanding the question and finding the equations

Answer 20

Hahah i know, i read it like 15 times!

Answer 21

do you by any chance know anything about calculating the amount of a loan after it's deferment period?

Answer 22

Ahhhh, finance isn't my strong spot, but ask the question and maybe someone else can also help! I'll try my best to help as well!

Answer 23

what i tried is simpler one, with reduced equations.. try that one..
