Answer:

Percent error is calculated using the formula:

Percent Error = ( |Predicted Value - Actual Value| / Actual Value ) * 100%

Plugging in Brianna's prediction and the actual number of puppies sold:

Percent Error = ( |16 - 9| / 9 ) * 100%

The absolute value of (16 - 9) is 7, so the calculation becomes:

Percent Error = ( 7 / 9 ) * 100%

This is approximately 77.78%, which is Brianna's percent error in her prediction.
