Answer 1

To find the percent error in Aatikah's prediction, we can use the formula for percent error:

\[ \text{Percent Error} = \frac{|\text{Actual Value} - \text{Predicted Value}|}{\text{Predicted Value}} \times 100% \]

In this case:

• Predicted Value = $30.00
• Actual Value = $19.75

Now, we can calculate the percent error:

1. Calculate the absolute difference: \[ |\text{Actual Value} - \text{Predicted Value}| = |19.75 - 30.00| = 10.25 \]

2. Now divide that by the predicted value and multiply by 100: \[ \text{Percent Error} = \frac{10.25}{30.00} \times 100% \approx 34.17% \]

Rounding to the nearest whole number: \[ 34% \]

None of the provided options seem to match this calculation. Let's verify the calculations:

• The calculation of the absolute difference is correct: $10.25.
• The calculation of the percent is correct: \( \approx 34.17% \).

Since none of the responses match 34%, it appears there might have been a mistake in the options provided. However, according to the options given:

1. 1%
2. 2%
3. 58%
4. 52%

The option that is closest to the provided calculated percent error (34%) isn't listed. Please double-check your options or calculations. Would you like assistance in reviewing the options or re-evaluating the question?

Answer 2
