Miguel Jenkins · Answer 1

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

Trent Banks · Answer 2

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

Then multiply by 100 to get the percentage, 30.43%
