Percent error is calculated by taking the difference between the predicted value and the actual value, dividing it by the predicted value, and then multiplying by 100.
Predicted value: $30.00
Actual value: $19.75
Difference: 30.00 - 19.75 = $10.25
Percent error: (10.25/30.00) * 100 ≈ 34.2
Round to the nearest whole number: 34

Your wrong
Apologies for the mistake. Let me recalculate the percent error correctly.
Predicted amount: $30.00
Actual amount: $19.75
Difference: $30.00 - $19.75 = $10.25
Percent error: (Difference / Predicted amount) * 100
Percent error: (10.25 / 30.00) * 100 ≈ 34.167
Rounding to the nearest whole number, the percent error in Aatikah's prediction is 34%.
