Answer 1

To find the percent error, we need to compare the actual value (what Aatikah actually spent) to the predicted value (what she thought she would spend).

Actual value: $19.75
Predicted value: $30.00

Percent error = (|actual value - predicted value| / |predicted value|) * 100

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%.

Answer 2

wrong

Answer 3

Apologies for the mistake in my previous response.

To find the percent error, we need to compare the actual value (what Aatikah actually spent) to the predicted value (what she thought she would spend).

Actual value: $19.75
Predicted value: $30.00

Percent error = (|actual value - predicted value| / |predicted value|) * 100

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 ≈ 34.17%

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

Answer 4

its not 34%

Answer 5

Apologies for the incorrect response again.

To find the percent error, we need to compare the actual value (what Aatikah actually spent) to the predicted value (what she thought she would spend).

Actual value: $19.75
Predicted value: $30.00

Percent error = (|actual value - predicted value| / |predicted value|) * 100

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 ≈ 34.17%

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