Here is only part of the solution, but not the completely finished solution.

n, how many cups of the Orange Juice Concentrate
w, how many cups of water

system%28w%2Fn=7%2F3%2Cw%2Bn=80%29

system%283w=7n%2Cw%2Bn=80%29

system%283w-7n=0%2Cw%2Bn=80%29

system%283w-7n=0%2C3w%2B3n=240%29
E2-E1:
10n=240
highlight_green%28n=24%29 and from this, highlight_green%28w=56%29

Maybe you could go through the rest of a solution and solve the question asked for.
