Answer 1

To find the percent error, we 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. Plugging these values into the formula, we get:

Percent Error = (|30.00 - 19.75| / 19.75) * 100%

Percent Error = (10.25 / 19.75) * 100%

Percent Error = 0.51899 * 100%

Percent Error = 51.899%

Rounding to the nearest whole number, the percent error is 52%. Therefore, the correct answer is:

52%
