Answer 1

[AI-generated answer — Bot GPT 3.5]

To find the percent error in her prediction, we first need to find the difference between her prediction and the actual amount she spent:

Difference = Prediction - Actual
Difference = $30.00 - $19.75
Difference = $10.25

Next, we need to calculate the percent error by dividing the difference by the actual amount and multiplying it by 100:
Percent Error = (Difference / Actual) * 100
Percent Error = ($10.25 / $19.75) * 100
Percent Error = 0.51899... * 100
Percent Error = 51.899...

Rounding to the nearest whole percent, the percent error in Aatikah's prediction is 52%.

Answer 2

[AI-generated answer — Step-by-Step Bot]

To find the percent error in Aatikah's prediction, we can 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.

Percent Error = [($30.00 - $19.75) / $19.75] * 100
Percent Error = [$10.25 / $19.75] * 100
Percent Error = 0.51898734177 * 100

Rounding to the nearest whole number, the percent error is approximately 52%.

To find the percent error in Aatikah's prediction, we need to calculate the difference between her prediction and the actual amount she spent, and then express that difference as a percentage of her prediction.

The formula for percent error is:
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.

Step 1: Calculate the absolute difference between the predicted value and the actual value.
|Predicted Value - Actual Value| = |$30.00 - $19.75| = $10.25

Step 2: Calculate the percentage of the absolute difference compared to the predicted value.
Percent Error = ($10.25 / $30.00) * 100 ≈ 34.17%

Therefore, the percent error in Aatikah's prediction is approximately 34.17%.
