    Answer:

    120 gallons of 10% fertilizer and 80 gallons of 20% fertilizer

    Step-by-step explanation:

    If x is gallons of 10% fertilizer, and y is gallons of 20% fertilizer, then:

    x + y = 200

    0.10x + 0.20y = 0.14(200)

    Solve with substitution:

    0.10x + 0.20(200 − x) = 0.14(200)

    0.10x + 40 − 0.20x = 28

    12 = 0.10x

    x = 120

    y = 80
