To find the percent error, we need to calculate the difference between the predicted amount and the actual amount, and then divide that difference by the predicted amount. Finally, we multiply the result by 100 to get the percentage.

The predicted amount is $30.00 and the actual amount spent is $19.75.
The difference is $30.00 - $19.75 = $10.25.

Now we calculate the percent error:
Percent error = (|Error| / Predicted amount) * 100
Percent error = ($10.25 / $30.00) * 100

Rounded to the nearest whole number, the percent error is 34%.

Therefore, none of the given options, 1%, 58%, 2%, and 52%, are correct.
please pick one
Apologies for the confusion. In that case, the closest option would be 1%.
