Aatikah plans to buy books at a book fair. She thinks she will need $30.00 to purchase the books. She only spends $19.75. Find the percent error in her prediction. Round your answer to the nearest whole number.(1 point)

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

\[ \text{Percent Error} = \left( \frac{|\text{Actual Value} - \text{Predicted Value}|}{\text{Predicted Value}} \right) \times 100 \]

In this case:

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

Now calculate the absolute error:

\[ |\text{Actual Value} - \text{Predicted Value}| = |19.75 - 30.00| = |-10.25| = 10.25 \]

Now plug the values into the formula:

\[ \text{Percent Error} = \left( \frac{10.25}{30.00} \right) \times 100 \]

Calculating this gives:

\[ \text{Percent Error} = \left( 0.34167 \right) \times 100 \approx 34.17 \]

Rounding to the nearest whole number gives 34%.

Therefore, the response options do not include 34%, but based on the calculations, the percent error Aatikah made in her prediction is approximately 34%.

If you only have the options 2%, 58%, or 52%, none of those are correct according to the calculations. However, based on the options given earlier, none of these answers are right based on the actual calculation of percent error.
