Percent Error = (Actual Value - Predicted Value) / Predicted Value * 100

Percent Error = ($19.75 - $30.00) / $30.00 * 100

Percent Error = -$10.25 / $30.00 * 100

Percent Error = -0.34 * 100

Percent Error = -34

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

Therefore, none of the given options (A, B, C, D) are correct.
