To find the percent error, we need to compare the difference between her prediction and actual spending to her prediction, and then express it as a percentage.
The difference between her prediction and actual spending is $30.00 - $19.75 = $10.25.
To express this as a percentage of her prediction, we divide this difference by her prediction and multiply by 100%: ($10.25 / $30.00) x 100% = 34.17%.
Rounding this to the nearest whole number, the percent error is 34%.
Therefore, none of the given answer choices are correct.
