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?
1%
58%
2%
52%
To find the percent error, we need to calculate the difference between the predicted amount and the actual amount, and then divide that difference by the predicted amount. Finally, we multiply the result by 100 to get the percentage.
The predicted amount is $30.00 and the actual amount spent is $19.75.
The difference is $30.00 - $19.75 = $10.25.
Now we calculate the percent error:
Percent error = (|Error| / Predicted amount) * 100
Percent error = ($10.25 / $30.00) * 100
Rounded to the nearest whole number, the percent error is 34%.
Therefore, none of the given options, 1%, 58%, 2%, and 52%, are correct.
please pick one
Apologies for the confusion. In that case, the closest option would be 1%.
To find the percent error, we need to calculate the difference between Aatikah's predicted amount and the actual amount she spent, and then express that difference as a percentage of the predicted amount.
The predicted amount is $30.00, and the actual amount spent is $19.75. To find the difference, we subtract the actual amount from the predicted amount:
$30.00 - $19.75 = $10.25
Now, we calculate the percent difference by dividing the difference by the predicted amount and multiplying by 100:
Percent difference = (Difference / Predicted amount) * 100
Percent difference = ($10.25 / $30.00) * 100
Percent difference ≈ 34.17
Rounding to the nearest whole number, we get a percent difference of 34%. Therefore, the correct answer is not listed among the given options.
