A 2%

B 1%

C 58%

D 52%

Answer 1

The percent error can be calculated using the formula:

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

In this case, the actual value is $19.75 and the predicted value is $30.00.

Percent Error = (|19.75 - 30.00| / 19.75) * 100
Percent Error = (10.25 / 19.75) * 100
Percent Error ≈ 51.9

Rounded to the nearest whole number, the percent error is 52%.

So, the correct answer is D 52%.
