To find the percent error, we need to calculate the difference between the predicted amount and the actual amount, and then divide that difference by the predicted amount.
The predicted amount is $30.00 and the actual amount spent is $19.75.
Difference = Predicted amount - Actual amount
Difference = $30.00 - $19.75
Difference = $10.25
Percent Error = (Difference / Predicted amount) * 100
Percent Error = ($10.25 / $30.00) * 100
Percent Error = 34.17%
Rounded to the nearest whole number, the percent error is 34%.
To find the percent error in Aatikah's prediction, we need to first calculate the difference between her predicted amount and the actual amount she spent, and then divide that difference by her predicted amount. Finally, we multiply the result by 100 to get the percentage.
The difference between her predicted amount ($30.00) and the actual amount she spent ($19.75) is $30.00 - $19.75 = $10.25.
Next, we divide the difference by her predicted amount: $10.25 / $30.00 = 0.34.
Finally, we multiply the result by 100 to convert it to a percentage: 0.34 * 100 = 34%.
Rounded to the nearest whole number, the percent error in Aatikah's prediction is 34%. Therefore, the correct answer is 34%.
