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

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%.

Answer 2

thats wrong

Answer 3

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%.
