To find the percent error, we need to compare the actual value (what Aatikah actually spent) to the predicted value (what she thought she would spend).
Actual value: $19.75
Predicted value: $30.00
Percent error = (|actual value - predicted value| / |predicted value|) * 100
Percent error = (|19.75 - 30.00| / |30.00|) * 100
Percent error = (|-10.25| / 30.00) * 100
Percent error = (10.25 / 30.00) * 100
Percent error = 0.342 * 100
Percent error ≈ 34.2%
Rounded to the nearest whole number, the percent error is 34%.
wrong
Apologies for the mistake in my previous response.

Percent error ≈ 34.17%

its not 34%
Apologies for the incorrect response again.

To find the percent error in Aatikah's prediction, we need to compare her predicted value ($30.00) to the actual value she spent ($19.75).
First, we need to calculate the difference between the predicted and actual values:
$30.00 - $19.75 = $10.25
Then, we can calculate the percent error by dividing the difference by the actual value and multiplying by 100:
($10.25 / $19.75) * 100 = 51.899%
Rounded to the nearest whole number, the percent error in Aatikah's prediction is 52%. Therefore, the correct answer is 52%.
