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 to the nearest whole number

Answer 1

Your wrong

Answer 2

Percent error is calculated by taking the difference between the predicted value and the actual value, dividing it by the predicted value, and then multiplying by 100.

Predicted value: $30.00
Actual value: $19.75

Difference: 30.00 - 19.75 = $10.25

Percent error: (10.25/30.00) * 100 ≈ 34.2

Round to the nearest whole number: 34

The percent error in her prediction is approximately 34%.

Answer 3

Apologies for the mistake. Let me recalculate the percent error correctly.

Predicted amount: $30.00
Actual amount: $19.75

Difference: $30.00 - $19.75 = $10.25

Percent error: (Difference / Predicted amount) * 100
Percent error: (10.25 / 30.00) * 100 ≈ 34.167

Rounding to the nearest whole number, the percent error in Aatikah's prediction is 34%.
