pure fruit juice?

You can put this solution on YOUR website! The expression "must be used to make" is misleading.
I assume that the company started with pure 100% juice.
Wouldn't it be easier and cheaper just to dilute some 100% juice to make the 60% juice drink instead of spending time and money to further dilute already prepared drinks. Basically, a poorly conceived and written problem.
.45x+.70y=.60*140
.45x+.70y=84
x+y=140

One would substitute during the use of two variables, giving one variable equation to solve anyway, so this could be done:
x, how much of the 45%
140-x, how much of the 70%
Accounting for amount of pure juice,
