Question 376144
One canned juice drink is 30% orange juice, another is 5% orange juice.
 How many liters of each should be mixed together in order to get 25 liters that is 9% of orange juice.
:
Let x = amt of 30% juice required
then
(25-x) = amt of 5% juice
:
.30x + .05(25-x) = .09(25)
:
.30x + 1.25 - .05x = 2.25
:
.30x - .05x = 2.25 - 1.25
.25x = 1
x = {{{1/.25}}}
x = 4 liters of 30% required
then
25 - 4 = 21 liters of 5% juice
