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 your answer to the nearest whole number.(1 point)

Answer 1

thats wrong

Answer 2

Apologies for the mistake. Let's recalculate the percent error.

Percent Error = ( ( Observed Value - Expected Value ) / Expected Value ) * 100

Observed Value = $19.75
Expected Value = $30.00

Percent Error = ( ( 19.75 - 30.00 ) / 30.00 ) * 100
Percent Error = ( -10.25 / 30.00 ) * 100
Percent Error = -34.17

Rounding this result to the nearest whole number, we get a percent error of -34%.

Answer 3

To find the percent error, we need to calculate the difference between the predicted value and the actual value, and then divide that by the predicted value. Finally, we multiply by 100 to express it as a percentage.

Predicted value = $30.00
Actual value = $19.75

Difference = Predicted value - Actual value = $30.00 - $19.75 = $10.25

Percent error = (Difference / Predicted value) * 100 = ($10.25 / $30.00) * 100 ≈ 34.1667

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

Answer 4

To find the percent error, we need to compare the difference between Aatikah's prediction and the actual amount she spent to her prediction, and then express that as a percentage.

The predicted amount is $30.00 and the actual amount spent is $19.75. So, we need to find the difference between these two amounts:

$30.00 - $19.75 = $10.25

Now, to calculate the percent error, we divide this difference by the predicted amount ($30.00) and multiply by 100 to get the percentage:

Percent Error = (Difference / Predicted Amount) * 100

Percent Error = ($10.25 / $30.00) * 100

Percent Error = 0.3417 * 100

Percent Error ≈ 34.17

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

Answer 5

Percent error is typically calculated using the formula:

Percent Error = ( ( Observed Value - Expected Value ) / Expected Value ) * 100

In this case, the observed value is $19.75 and the expected value is $30.00.

Using the formula, we can calculate the percent error as follows:

Percent Error = ( ( 19.75 - 30.00 ) / 30.00 ) * 100
Percent Error = ( -10.25 / 30.00 ) * 100
Percent Error = -0.342 * 100
Percent Error = -34.2

Rounding this result to the nearest whole number, we get a percent error of -34%.
