A university football stadium has 81,500 seats. The stadium is at full capacity on game day. Layla believes only 79,000 seats are occupied. Find the percent error of Layla's prediction.

Answer 1

Percent error is calculated by taking the absolute difference between the estimated value and the actual value, dividing it by the absolute value of the actual value, and then multiplying by 100%.

The actual value is 81,500 and the estimated value is 79,000.

Absolute difference = |79,000 - 81,500| = |-2,500| = 2,500
Absolute value of actual value = |81,500| = 81,500

Percent error = (2,500/81,500) * 100% = 3.07%

The percent error of Layla's prediction is 3.07%.
