To find the percent error, we need to find the difference between the predicted amount and the actual amount, and then divide that by the predicted amount. The difference is $30.00 - $19.75 = $10.25.

So the percent error is (10.25/30) * 100 = 34.17%.

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