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%.
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%.

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%.
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

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