Answer: 23 %
Step-by-step 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=[tex]\frac{\text{error value}}{\text{actual cost}}\times100[/tex]
[tex]=\frac{\$15}{\$65}\times100[/tex]
[tex]=23.0769\%\approx23\%[/tex]
Therefore, the percent error =23%
