one can juice is 30% juice and another is 5% juice. How many liters of each should be mixed togther to get 25liters that is 28%juice
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The equation of the pure juice content is this
0.3x + 0.05*(25-x) = 0.18*25,
where x is unknown volume in liters of the 30% juice.
Simplify and solve:
0.3x + 0.05*25 - 0.05x = 4.5,
0.25x + 1.25 = 4.5 ---> 0.25x = 4.5 - 1.25 ---> 0.25x = 3.25 ---> x = = 13.
Answer. 13 liters of the 30% juice and (25-13) = 12 liters of the 5% juice.
