Hi, Bill,  

My instructions to questioners include:

(5) Tell me what you already did, and what you are studying -- don't just say Math -- I know that already. What section of the text is this from?  

Since you didn't tell me what you already tried to do, I must conclude that you only need to get started.

Here's how to get started:

Write:
Let  J = the cost of one case of juice.

[Don't write 'x' if you can use a better symbol.
and don't be lazy -- don't write Let J = juice.]
 
Let W = the cost of one case of water.

Then (and I mean write those words 'Let' and 'Then'.  

2J = the cost of 2 cases of juice,

etc.
