Question

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)

Answer 1

To find the percent error in Aatikah's prediction, we need to calculate the difference between her predicted amount ($30.00) and the actual amount she spends ($19.75).

$30.00 - $19.75 = $10.25

Then, we find the percent error by dividing the difference by the predicted amount and multiplying by 100.

Percent Error = (actual - predicted) / predicted * 100

Percent Error = ($10.25 / $30.00) * 100

Percent Error ≈ 34.17

Rounded to the nearest whole number, the percent error is 34%.
