A. 1%
B. 2%
C. 58%
D. 52%
To find the percent error in her prediction, we subtract the actual value ($19.75) from the predicted value ($30.00), then divide by the predicted value and multiply by 100.
Percent error = (Predicted value - Actual value) / Predicted value * 100
Percent error = ($30.00 - $19.75) / $30.00 * 100
Percent error = $10.25 / $30.00 * 100
Percent error ≈ 34.17%
Rounding to the nearest whole number, we get 34%.
Therefore, the correct answer is not listed.
