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
58%

To find the percent error, we need to calculate the difference between the predicted value and the actual value, then divide that difference by the actual value and multiply by 100.
The predicted value is $30.00, and the actual value is $19.75.
Difference = Predicted value - Actual value
= $30.00 - $19.75
= $10.25
Percent Error = (Difference / Actual value) * 100
= ($10.25 / $19.75) * 100
= 52%
Therefore, the percent error in Aatikah's prediction is 52%.
To find the percent error in Aatikah's prediction, we need to calculate the difference between her predicted amount and the actual amount she spent, and then express that difference as a percentage of her predicted amount.
First, let's calculate the difference by subtracting the actual amount spent from the predicted amount:
30.00 - 19.75 = 10.25
Next, we need to calculate the percent that the difference represents of the predicted amount:
(10.25 / 30.00) × 100 = 34.17%
Now, we round the percentage to the nearest whole number, which is 34.
Therefore, the correct answer is 34%.
Your wrong that answer is not on my screen. Use one of the options I gave u ur wrong dude
To find the percent error, we use the formula:
Percent Error = (|Observed Value - Predicted Value| / Predicted Value) * 100
In this case, the observed value is $19.75 and the predicted value is $30.00.
Percent Error = (|19.75 - 30.00| / 30.00) * 100
Percent Error = (|-10.25| / 30.00) * 100
Percent Error = (10.25 / 30.00) * 100
Percent Error = 0.342 * 100
Percent Error = 34.2
Rounded to the nearest whole number, the percent error is 34%.
So the correct answer is not in the given options.
