Question

HELP! I'll fan and give a medal

Answer 1

HI!!

Answer 2

this is like the tenth time i have seen this question, maybe i should make a template for it

Answer 3

first off it says "Write an equation in one variable " and your equation has two , so lets start again

Answer 4

Ok, other than that, am I on the right track?

Answer 5

secondly it has "find the total number of liters of apple juice and water in the jar. " which is stupid because you know the number of liters of water right?

Answer 6

Yea, 1 right? And there's 3 of juice?

Answer 7

yeah so it is easy enough to solve in your head
one liter of water, 3 liters of juice makes 75% juice
but i guess you still have to come up with an equation that they like

Answer 8

lets see if we can do that, even though it is not necessary to write an equation to solve this rather simple question

Answer 9

we can call the number of liters of juice \(j\) if you like, since that is what you have to find

Answer 10

that means \[j+1\] is the total amount right?

Answer 11

Yea

Answer 12

and since it has to be \(75\%\) juice we also know \(j\) must equal
it must be \(.75(J+1)\)

Answer 13

set
\[j=.75(j+1)\] and solve for \(j\)

Answer 14

3

Answer 15

you will get \(j=3\) when you solve that, just like you knew at the beginning without resorting to this rather silly equation

Answer 16

yeah you got it

Answer 17

Oh ok. So that's the equation?

Answer 18

that is one you can use, yes
and it does only have one variable

Answer 19

j=.75(j+1)=3

Answer 20

oh no, not = 3

Answer 21

solve
\[j=0.75(j+1)\] and you will get \(j=3\) as the solution

Answer 22

Ohh ok. Makes sense.

Answer 23

good!

Answer 24

And just to make sure this would be part B?

j = .75(j + 1)
j = .75j + .75
j - .75j =.75
0.25j = .75
j = 3
