Alton estimated that 230 people attended the band concert. The actual count for attendance was 200 people. Find the percent of error.

Answer 1

To find the percent of error, we need to calculate the difference between the estimated and actual count as a percentage of the actual count.

The difference between the estimated and actual count is:
230 - 200 = 30 people

To find the percent of error, we divide the difference by the actual count and multiply it by 100:
(30/200) * 100 = 15%

The percent of error is 15%.
