One canned juice drink contains 30% orange juice; another is 10% orange juice. How many liters of each should be mixed together in order to get 20L that is 28% orange juice?
I want step by step help.

Work with the amount of juice in each mixture. Add up the juice in the parts, and it must equal the juice in the final mixture. If there are x liters of 30% juice, there are 20x liters of 10% juice:
.30x + .10(20x) = .28(20)
just solve for x to answer the questions.
