To find the percent error, we first subtract the predicted value from the actual value:
$30.00 - $19.75 = $10.25
Then, we divide the difference by the predicted value and multiply by 100 to get the percent:
($10.25 / $30.00) * 100 ≈ 34.17%
Rounding to the nearest whole number, the percent error is 34%.
wrong
Apologies for the mistake.
To find the percent error, we first subtract the actual value from the predicted value:
$19.75 - $30.00 = -$10.25
Since the result is negative, we take the absolute value:
| -$10.25 | = $10.25
Then, we divide the absolute difference by the predicted value and multiply by 100 to get the percent:
($10.25 / $30.00) * 100 ≈ 34.17%
Rounding to the nearest whole number, the percent error is also 34%.
