    The way you figure out percent increase is you take the final number, divide it by the original number, and then subtract 1 from the result.

    Therefore, in this question, take the final number of 450, divide it by the original number, 200, and then subtract 1.

    450 : 200 - 1 =

    2.25 - 1 =

    1.25

    1.25 is the same thing as 125%, so Jay increased the number of dogs he groomed by 125%.
