Attica plans to buy books at the book fair she think she will need $30 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 need to calculate the difference between the predicted amount and the actual amount, and then express it as a percentage of the predicted amount.

Predicted amount: $30
Actual amount spent: $19.75

Difference = Predicted amount - Actual amount spent
Difference = $30 - $19.75 = $10.25

Percent error = (Difference / Predicted amount) * 100

Percent error = ($10.25 / $30) * 100

Percent error ≈ 34.17%

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