To find the percent error of Layla's prediction, we can use the formula for percent error:
\[ \text{Percent Error} = \left( \frac{|\text{Actual Value} - \text{Predicted Value}|}{\text{Actual Value}} \right) \times 100 \]
In this case:
- Actual Value = 81,500 (the full capacity of the stadium)
- Predicted Value = 79,000 (Layla's belief on occupied seats)
Now, we calculate the absolute error:
\[ |\text{Actual Value} - \text{Predicted Value}| = |81,500 - 79,000| = 2,500 \]
Next, we plug the values into the percent error formula:
\[ \text{Percent Error} = \left( \frac{2,500}{81,500} \right) \times 100 \]
Calculating the fraction:
\[ \frac{2,500}{81,500} \approx 0.0307 \]
Now multiply by 100 to get the percent:
\[ \text{Percent Error} \approx 0.0307 \times 100 \approx 3.07 \]
Finally, rounding to the nearest hundredth of a percent gives us:
\[ \text{Percent Error} \approx 3.07% \]
Thus, the percent error of Layla's prediction is approximately 3.07%.
