    The answer to the question is;

    1.5 gallons of 100% lemon juice added to 2.5 gallons of 20% lemon juice + 80% lime juice to make 4 gallons of the 50% lemon/50% lime juice mixture.

    1.5 gallons of 100% lemon juice

    Step-by-step explanation:

    To solve the question, we note

    Desired concentration = 50% lemon juice and 50% lime juice

    Available concentration = 100% lemon juice and 20% lemon juice and 80% lime juice

    To make 4 gallons of 50% lemon juice and 50% lime juice Milo requires

    20 per 100 lemon requires 60 parts of pure lemon to make 160 parts of 50% lemon juice and 50% lime juice

    100 requires 60 to make 160

    100/160 requires 60/160 to make one part of 50% lemon juice and 50% lime juice

    That is 5/8 gallon of 20 % lemon requires 3/8 gallon of pure lemon to make 1 gallon of 50% lemon juice and 50% lime juice

    That is 2.5 gallons of 20 % lemon requires 1.5 gallons of pure lemon to make 4 gallons of 50% lemon juice and 50% lime juice

    Milo should add 1.5 gallons of 100% lemon juice to 2.5 gallons of a juice mixture that is 20% lemon juice and 80% lime juice to make 4 gallons of the 50% lemon/50% lime juice mixture

    1.5gal

    Step-by-step explanation:

    From the given information:

    50% lemon juice + 50% lime juice is the intended mixture.

    Therefore, to find quantity that would be added to 20% lemon juice and 80% lime juice, let's assume this to be x.

    x of 100% and 4-x gallons of the existing 20% mix

    100%x + 20% (4-x) = 50% (4)

    1.00x + 0.2 (4-x) = 0.5 (4)

    1.00x + 0.8-0.2x = 2

    1.00x-0.2x = 2-0.8

    0.8x = 1.2

    * = 1.5gal.
