To find the percent error, we can use the formula:
Percent Error = ( | Predicted Value - Actual Value | / Actual Value ) x 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 ) x 100%
= ( 10.25 / 19.75 ) x 100%
≈ 0.5197 x 100%
≈ 51.97%
Rounding this to the nearest whole number, the percent error is approximately 52%.
Therefore, the correct answer is D. 52%.
