C. 2%
D. 58%
To find the percent error, we first need to calculate the difference between the predicted amount and the actual amount spent.
Predicted amount = $30.00
Actual amount spent = $19.75
Difference = Predicted amount - Actual amount spent
Difference = $30.00 - $19.75
Difference = $10.25
Next, we need to find the percent of this difference relative to the predicted amount.
Percent error = (Difference / Predicted amount) x 100
Percent error = (10.25 / 30.00) x 100
Percent error = 0.342 x 100
Percent error = 34.2
Rounding this to the nearest whole number, the percent error is 34%.
Therefore, the correct answer is not given in the options.
