I think you can do something like $.8t = 1$ where $t$ is the total amount of stuff in the bottle.

I think I have to put all the numbers in one equation.  Then I solve it.. I can solve it, I just don't know what to write for the equation.

What's wrong with the one I wrote? :D

It doesn't have the 20% and stuff. o:

anonymous · Answer

It says one variable. So I used the total amount of stuff in the bottle as the one variable. You can get the amount of milk by doing $.2t$ because milk is 20%, and it's really just making the problem more contrived to do anything else.

A bottle of 20% milk and 80% water sounds disgusting anyway.
