To find the percent error, we can use the formula:
Percent Error = (|Predicted Value - Actual Value| / Actual Value) * 100%
In this case, the predicted value is $30.00 and the actual value is $19.75.
Using the formula, we can calculate the percent error:
Percent Error = (|30.00 - 19.75| / 19.75) * 100%
Percent Error = (10.25 / 19.75) * 100%
Percent Error = 0.519 * 100%
Percent Error = 51.9%
Rounding to the nearest whole number, the percent error is 52%.
