## anonymous one year ago Help me please!! I will medal and fan!! Meg has a can that contains 80% of orange juice and the rest water. The can has 1 liter of water. SCROLL ALL THE WAY DOWN TO SEE MY QUESTION Part A: Write an equation in one variable that can be used to find the total number of liters of orange juice and water in the can. Define the variable used in the equation. (5 points) Part B: How many liters of orange juice are present in the can? Show your work.

• This Question is Open
1. Plasmataco

y=4x.

2. Plasmataco

think about it. 80 percent is 4 times 20 percent.

3. anonymous

ok

4. Plasmataco

4*1=4 (part 2)

5. anonymous

following u

6. anonymous

Write an equation in ONE variable that can be used to find the total number of liters of orange juice and water in the can

7. anonymous

what??

8. anonymous

plz help @Plasmataco

9. anonymous

what the heck does $$y=4x$$ mean in this context?

10. anonymous

i dont know?

11. anonymous

me neither

12. anonymous

lets go slow, read the question carefully, name a variable, and see if we can come up with an equation that solves what we are looking for

13. anonymous

ok

14. Plasmataco

oh. Well, picture it in your head. If 80% is OJ, how much percent is water?

15. anonymous

20??

16. anonymous

the question asks, "Write an equation in one variable that can be used to find the total number of liters of orange juice and water in the can"

17. Plasmataco

ok.

18. Plasmataco

so isn't there 4 times more OJ than water?

19. anonymous

we actually know the liters of water in the can, it is 1 as you are told that so what we need to find is the number of liters of orange juice in the can

20. Plasmataco

so if there is one liter of water, there should be 4 time more in OJ

21. anonymous

now as @Plasmataco said, after he wrote that nonsense about $$y=4x$$ which has nothing to do with this, there is in fact 4 times more oj than water, so since there is one liter of water there must be 4 liters of ok, the total being 5 liters lets still come up with an equation that we can solve

22. Plasmataco

1*4=4

23. Plasmataco

and woah! don't attack me. I wuz tryin halp.

24. anonymous

if we put say $$x$$ as the number of liters of OJ, then we know two things first we know $$x+1$$ is the total number of liters of mix, and we know that $$80\%$$ of it is OK, so we know $0.8\times (x+1)=x$

25. anonymous

if you solve that equation in ONE variable (which we have defined as $$x=$$ the number of liters of OJ we will get $$x=4$$

26. Plasmataco

...

27. Plasmataco

1*4

28. Plasmataco

whatevs, we're both right.

29. Plasmataco

XD

30. anonymous

so confused omg

31. Plasmataco

just... 4 liters of orange juice and 0.8*(x+1)=x

32. anonymous

ok? so .8 times (x plus one) equals x?

33. Plasmataco

or... if you want to take it really simple, X=4*1. You should probably use the other one. XD

34. anonymous

thx

35. Plasmataco

no problem

36. anonymous

^^ @pooja195 but the question asks for an equation that gives me the total liters, oj+water in the can, so would x=.8x(t+1) be right, if t=oj and x=total amount?

37. anonymous

@Hero ??

38. anonymous

pleease? @Hero ? can u suggest any1 to help?

39. anonymous

no... well, i just dont know if he got the message of the question :( read my last comment... @Hero

40. anonymous

and not anymore
