Answer: 23 %

Explanation:

Given : James estimated the total cost of groceries to be $50.

The actual cost of groceries = $65

The error value in the total cost= actual cost - estimated value

=$65-$50

Therefore, Error value=$15

The percent error=
$\frac{\text{error value}}{\text{actual cost}}*100$

$=(\$15)/(\$65)*100$

$=23.0769\%\approx23\%$

Therefore, the percent error =23%
