Answer 1

I don't understand this line

"He will invest 40% of the total between Zycodec and Xenon in the Unix stock"

Answer 2

:/

Answer 3

OMGGGGGG IHATE MATHHHHHHHHHH

Answer 4

lol

Answer 5

are you sure those are the exact words?>

Answer 6

Yes, why wouldn't they be? I copied and pasted

Answer 7

well, I get this

Z + X = SOME AMOUNT
U = 40% SOME AMOUNT => U = (Z+X)0.4

now twice as much of Z goes to X
so X = 2Z

Answer 8

ahh ok I see what its saying

Answer 9

so
Z + X + U = 1617

but X = \(\color{blue}{2Z}\)
and U = (Z + X) => ( Z + \(\color{blue}{2Z}\))

Answer 10

hmm, actually and U = (Z + X) => ( Z + \(\color{blue}{2Z}\))(0.4)

Answer 11

which is 40% of the total of Zycoden and Xenon stocks

Answer 12

so
Z + X + U = 1617
or
Z + 2Z + (Z + 2Z)(0.4) = 1617

then just solve for "Z"

Answer 13

omfg

Answer 14

hehe

Answer 15

z + 2z + (z+2z)(0.4)

Answer 16

Lower case makes it better but I still don't understand

Answer 17

once you find Z, zycodec amount
to get Unix stock amount, well, U = (Z + 2Z)0.4

Answer 18

Idk how to find z

Answer 19

is just plain simplifying

Answer 20

the Xenon stock is based on the Zycodec, 2 to 1, so Xenon's is twice as much or 2Z

the total amount invested in Zycodec and Xenon is , Zycodec's plus Xenon
or Z + 2Z

Answer 21

and the Unix stock is based on their total, 40% of it

Answer 22

B. $462
????

Answer 23

yes

Answer 24

Zycodec's amount is $385
thus

0.4 or 2/5

2/5 ( 385 + 770) => 462
