To find the percent error, we need to find the difference between the predicted amount and the actual amount (in absolute value), divide that by the predicted amount, and then multiply by 100 to get a percentage.
The difference between the predicted amount and the actual amount is $30.00 - $19.75 = $10.25.
The percent error is then (10.25 / 30.00) * 100 = 34.17.
Rounding to the nearest whole number, the percent error is 34%.
So the correct answer is 34%.
To find the percent error in Aatikah's prediction, we need to compare her predicted value with the actual value and calculate the difference as a percentage of the actual value.
First, let's calculate the difference between her predicted amount and the actual amount she spent:
Difference = Predicted amount - Actual amount
Difference = $30.00 - $19.75
Difference = $10.25
Next, we need to calculate the percent error. Percent error is calculated by taking the absolute value of the difference and dividing it by the actual value, then multiplying by 100.
Percent Error = (|Difference| / Actual value) * 100
Percent Error = (|$10.25| / $19.75) * 100
Percent Error = (10.25 / 19.75) * 100
Percent Error ≈ 51.90
Rounding this to the nearest whole number, the percent error in Aatikah's prediction is 52%.
The percent error can be calculated using the formula:
Percent Error = (Actual Value - Predicted Value) / Actual Value * 100
In this case, the actual value of Aatikah's purchase is $19.75, and the predicted value is $30.00.
Using the formula:
Percent Error = (19.75 - 30.00) / 19.75 * 100
Calculating this expression:
Percent Error = (-10.25) / 19.75 * 100
Percent Error = -52.00
Rounding this to the nearest whole number:
Percent Error = -52
Therefore, the percent error in Aatikah's prediction is 52%.
