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.

  • Math -

    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 20-x liters of 10% juice:

    .30x + .10(20-x) = .28(20)

    just solve for x to answer the questions.
