To calculate the percentage error, we first need to find the absolute error, which is the absolute value of the difference between the predicted value and the actual value.

Absolute error = |predicted value - actual value|
Absolute error = |38 - 40|
Absolute error = 2

Next, we calculate the percentage error using the formula:

Percentage error = (absolute error / actual value) x 100
Percentage error = (2 / 40) x 100
Percentage error = 0.05 x 100
Percentage error = 5%

Therefore, the percentage error in this case would be 5%.
