    (Experimental-Estimate) / Estimate = (300-230) / 230=.3043

    Then multiply by 100 to get the percentage, 30.43%

    First find the numerical difference between the estimate and the actual attendance numbers.

    300-230 = 70

    What percentage of the estimated attendance is 70?

    70/230 =.3043 = 30.43% error
