The percent error can be calculated as follows:
Percent Error = ((Actual Value - Predicted Value) / Predicted Value) * 100
Given that the predicted value is $30.00 and the actual value is $19.75, we can substitute these values into the formula:
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 to the nearest whole number, the percent error is -34%.
Therefore, none of the given options are correct.
