To find the percent error, we need to subtract the actual amount spent from the predicted amount, divide it by the predicted amount, and then multiply by 100 to get the percentage.

Percent error = (Actual amount - Predicted amount) / Predicted amount * 100

In this case, the actual amount spent is $19.75 and the predicted amount is $30.00.

Percent error = (19.75 - 30.00) / 30.00 * 100

Percent error = -10.25 / 30.00 * 100

Percent error = -0.3417 * 100

Percent error = -34.17

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

Therefore, the correct answer is 34%.
