Answer 1

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.

Percent Error = (|$30.00 - $19.75| / $19.75) × 100
Percent Error = ($10.25 / $19.75) × 100
Percent Error ≈ 51.9

Rounding to the nearest whole number, the percent error is 52%.

Therefore, the correct answer is:

52%
