At the beginning of the year last year a math department budget was 15% of the total budget. This year it was 10% of the total budget. What percet did the math department budget decrease from last year?

  • Math - , Wednesday, September 4, 2013 at 6:33pm

    (10%/15%)*100%=(10/15)*100%=
    66.67%.

    66.67% - 100%=-33.33% or 33.33% Decrease

    Another Approach:

    %Decrease = ((15%-10%)/15%)*100% =
    (5/15)*100% = 33.33%
