Correct answer?
To find the percent error, we need to first determine the difference between the predicted amount and the actual amount.
Predicted amount = $30.00
Actual amount = $19.75
The difference is:
$30.00 - $19.75 = $10.25
Next, we calculate the percent error by dividing the difference by the predicted amount and multiplying by 100:
Percent error = ($10.25 / $30.00) * 100 ≈ 34.17%
Rounded to the nearest whole number, the percent error is 34%.
Therefore, none of the given options is the correct answer.
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.
Therefore, the percent error is:
Percent Error = (|$30.00 - $19.75| / $19.75) * 100
Percent Error = ($10.25 / $19.75) * 100
Percent Error = 0.51898734 * 100
Percent Error = 51.898734
Now, rounding this percent error to the nearest whole number, we get:
Percent Error ≈ 52%
Therefore, the correct answer is "52%."
To find the percent error, we need to determine the difference between the predicted amount and the actual amount, and then divide that difference by the predicted amount and multiply by 100.
Predicted amount: $30.00
Actual amount: $19.75
Difference: $30.00 - $19.75 = $10.25
Percent error: ($10.25 / $30.00) * 100 ≈ 34.17%
Rounded to the nearest whole number, the percent error is 34%. Therefore, the correct answer is not any of the options provided.
