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.

Answer 1

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}.
