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) Responses 58% 58% 1% 1% 52% 52% 2%

Answer 1

To find the percent error, we can use the formula:

percent error = (actual - predicted) / predicted * 100%.

In this case, the actual amount Aatikah spent is $19.75 and her predicted amount is $30.00.

percent error = (19.75 - 30.00) / 30.00 * 100%

percent error = -10.25 / 30.00 * 100%

percent error ≈ -0.3416667 * 100%

percent error ≈ -34.16667%

Rounding to the nearest whole number, the percent error is approximately -34%.
