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.

Answer 1

To find the percent error in her prediction, we first need to find the difference between her prediction and the actual amount she spent:
Difference = Prediction - Actual
Difference = $30.00 - $19.75
Difference = $10.25

Next, we need to calculate the percent error by dividing the difference by the actual amount and multiplying it by 100:
Percent Error = (Difference / Actual) * 100
Percent Error = ($10.25 / $19.75) * 100
Percent Error = 0.51899... * 100
Percent Error = 51.899...

Rounding to the nearest whole percent, the percent error in Aatikah's prediction is 52%.
