Answer
The percent error for Wesley's estimate is 8.5%.
Solution
Percent error is calculated as the absolute value of the difference between the estimated value and the actual value divided by the actual value, then multiplied by 100.
Here are the steps:
1. Find the absolute difference: |50 - 46.10| = 3.90.
2. Divide by the actual value: 3.90 / 46.10 ≈ 0.0846.
3. Multiply by 100 to get the percent error: 0.0846 × 100 ≈ 8.46%.
Rounded to the nearest tenth, the percent error is 8.5%.

To find the percent error, you can use the formula: \[ \text{Percent Error} = \left(\frac{|\text{Estimated Value} - \text{Actual Value}|}{\text{Actual Value}}\right) \times 100 \] Substituting Wesley’s values into the formula: \[ \text{Percent Error} = \left(\frac{|50 - 46.10|}{46.10}\right) \times 100 = \left(\frac{3.90}{46.10}\right) \times 100 \approx 8.5\% \] So, the percent error for Wesley's estimate is approximately \( 8.5\% \).
