To find the percentage error, you first need to calculate the difference between the actual value and the predicted value.
The actual number of occupied seats is 81,500 and Layla predicted 79,000.
Difference = Actual Value - Predicted Value
Difference = 81,500 - 79,000
Difference = 2,500
Next, you need to find the percentage of the difference relative to the actual value.
Percentage Error = (Difference / Actual Value) * 100%
Percentage Error = (2,500 / 81,500) * 100%
Percentage Error ≈ 3.07%
Therefore, the percentage error of Layla's prediction is approximately 3.07%.
