To find the percent error, we first need to find the absolute difference between the predicted amount and the actual amount:

$30.00 - $19.75 = $<<30-19.75=10.25>>10.25

Then, we divide this difference by the predicted amount and multiply by 100%:

(10.25 / 30) * 100% ≈ 34.17%

Rounding to the nearest whole number, the percent error is 34%. Answer: \boxed{34}.

To find the percent error in Aatikah's prediction, we need to compare her prediction with the actual amount she spent.

First, let's find the difference between her prediction and the actual amount:
Actual amount = $19.75
Prediction = $30.00

Difference = $30.00 - $19.75 = $10.25

Next, we'll calculate the absolute value of the difference since percent error is always positive:
Absolute Difference = |$10.25| = $10.25

To calculate the percent error, we need to divide the absolute difference by the actual amount and multiply by 100:
Percent Error = (Absolute Difference / Actual amount) x 100

Percent Error = ($10.25 / $19.75) x 100 = 0.5189873424 x 100 ≈ 51.90

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

Answer 3

[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.

So, let's substitute these values in the formula:

Percent Error = (($30.00 - $19.75) / $19.75) * 100

Percent Error = ($10.25 / $19.75) * 100

Percent Error = 0.51899 * 100

Percent Error ≈ 51.9 (rounded to the nearest whole number)

Therefore, the percent error in Aatikah's prediction is approximately 51.9%.
