Thread: Word Problem

One canned juice drink is 25% O.J, another is 10% O.J. How many liters of each should be mixed together in order to get 15L that is 21% O.J.?

Anyone? I really need help with this problem. It is the last question. Thank you.

and

(this is the amount of juice in the product)

Now your problem is to solve these simultaneous linear equations.
