Answer 1

The percent error in the principal's estimate is 20%.

Step-by-step explanation:

To calculate the percent error, we need to find the difference between the actual value and the estimated value, and then divide that difference by the actual value.

In this case, the actual number of people who attended the concert was 112, and the estimated number was 90.

The percent error can be calculated as follows:

Percent Error = ((112 - 90) / 112) × 100 = 19.64%. Rounding to the nearest whole number, the percent error is 20%.
