    Percentage increase

    A worker's salary increases from $72000 to $81000. What is the percentage increase?



    Code:
    81000 - 72000 = 9000
    9000 / 81000 = 0.11111111
    0.11111111 x 100 = 11.111%
    My scientific calculator gives me the answer 11.111%, but on online calculators the answer is 12.5% So what is the correct answer? :-)

    9000 / 72000 = .125, so 12.5%

    Oh, snap! I must have misread it every time.

    % Increase = increase / original price x 100%

    Thank you. :-)
