    Short Answer: D

    Solution

    Difference in weight = 8.68 - 6.2 = 2.48 pounds

    %increase = x

    6.2 * x/100 = 2.48 Divide by 6.2 on both sides

    (6.2 * x / 100) : 6.2 = 2.48 / 6.2 Simplify the left. Divide the right.

    x / 100 = 0.4 Multiply both sides by 100

    100 * x / 100 = 0.4 * 100 Combine

    x = 40 %

    Answer

    The Puppy went up 40% in weight.

    D because 6.2=100

    6.2*1.4=8.68

    so 100*1.4=140

    140-100=40

    so it's 40%
