One canned juice drink is 20% orange juice! another is 5% orange juice. How many liters of each should be mixed together in order to get 15L that is 16% orange juice?

  • Algebra - ,

    amount of 20% juice used ...... x L
    amount of 5% juice used ....... 15 - x L

    .20x + .05(15-x) = .16(15)
    times 100 to get rid of those decimals
    20x + 5(15-x) = 16(15)
    20x + 75 - 5x = 240
    15x = 165
    x = 11

    Answer as needed.
