First, we need to find the difference between Aatikah's prediction and her actual spending.
$30.00 - $19.75 = $<<30-19.75=10.25>>10.25
Next, we need to find the percent error by dividing this difference by her prediction, and then multiplying by 100.
Percent error = (10.25 / 30.00) * 100
Percent error = 0.342 * 100
Percent error = 34.2
Since we are rounding to the nearest whole number, the percent error is 34%.
Therefore, none of the given answer choices match the correct percent error.
