Part A: Write an equation in one variable that can be used to find the total number of liters of lemon juice and water in the bottle. Define the variable used in the equation.

Part B: How many liters of lemon juice are present in the bottle? Show your work.

Answer 1

HI!!

Answer 2

the total number of liters of water is not something you have to find, it is 1 liter
what you have to find is the liters of lemon juice
name a variable, and say that it represents the number of liters of lemon juice

Answer 3

j=lemon juice

Answer 4

what do you want to call your variable? ok J = liters of lemon juice, fine

Answer 5

t= total amount of juice

Answer 6

you don't need two variables, one will do

Answer 7

especially since it says
"Write an equation in ONE variable "

Answer 8

ok, but we have to find the total of lemon juice and water, not just lemon juice, so i didnt knoe...

Answer 9

if J is the amount of lemon juice and there is one liter of water, then the total amount is
\[J+1\] which is why you don't need another variable

Answer 10

ok

Answer 11

then \(60\%\) of the total is lemon juice, the total is \(J+1\) so you can write an equation
\[J=0.6\times (J+1)\] and solve that for \(J\)

Answer 12

if you do it correctly you should get \(J=1.5\)

Answer 13

ok so first I would subtract?

Answer 14

because I need to do the work

Answer 15

please help

Answer 16

Like @misty1212 said,

"J=0.6×(J+1)

and solve that for J"

First step is

J=0.6J+0.6

OK?

Answer 17

okk?

Answer 18

What do you think the next step is then?

Answer 19

subtract 1?

Answer 20

@sdfgsdfgs

Answer 21

no, group all terms with the variable J on to one side....

Answer 22

?ok.. how do i do that

Answer 23

J=0.6J+0.6
so which term includes the variable J

Answer 24

0.6j? @sdfgsdfgs

Answer 25

And J on the left hand side!

Move them all to one side but subtracting 0.6J

Answer 26

ok

Answer 27

What do you get after that?

Answer 28

j=.6?

Answer 29

@sdfgsdfgs

Answer 30

please?

Answer 31

J=0.6J+0.6

subtract 0.6J on the left and right hand side

Answer 32

j-6j=.6

Answer 33

what is the left side equal to?

Answer 34

0.6?

Answer 35

That is the right side. how about the left?

Answer 36

j-.6j

Answer 37

what is that equal to?

Answer 38

.6
