Answer 1

To find the percent error, use the formula:

Percent Error = (|Observed Value - Predicted Value| / Predicted Value) x 100

In this case, the observed value is $19.75 and the predicted value is $30.00.

Percent Error = (|19.75 - 30.00| / 30.00) x 100

Percent Error = (|-10.25| / 30.00) x 100

Percent Error = (10.25 / 30.00) x 100

Percent Error ≈ 0.34 x 100

Percent Error ≈ 34%

Therefore, the closest whole number percent error is 34%.
