Problema Solution
One canned juice drink is 25% juice; another is 5% orange juice. How many liters of each should be mixed together in or to get 20L that is 12% orange juice
Answer provided by our tutors
Ley x, y be the liters of 25%, 5% juices.
x+y=20.
0.25x+0.05y=0.12*20.
0.25x+0.5y=2.4
25x+5y=240
From equation 1 , y=20-x.
25x+5(20-x)=240.
25x+100-5x=240.
20x=240-100.
20x=140..
x=140/20=7 liters.
y=20-7
=13 liters.
