    Answer: The weight of the box is 0.2 pounds and the weight of the chocolates before any chocolates were taken out is 2 pounds

    Step-by-step explanation:

    Let x represent the weight of the box only.

    The weight of the box of chocolates is 2.2 pounds. It means that the weight of the chocolate only is

    (2.2 - x) pounds

    After taking out 75% of the chocolates, the remaining chocolates and the box weigh 0.7 pounds. It means that

    2.2 - 0.75 (2.2 - x) = 0.7

    2.2 - 1.65 + 0.75x = 0.7

    0.75x = 0.7 + 1.65 - 2.2

    0.75x = 0.15

    x = 0.15/0.75

    x = 0.2 pounds

    The weight of the chocolates before any chocolates were taken out is

    2.2 - x = 2.2 - 0.2 = 2 pounds
