Solution: We are given:
Predicted Sales by Sameera [tex]=38[/tex]
Actual Sales by Sameera [tex]=28[/tex]
Now to find the Percent error, we have to use the below formula:
[tex]Percent-Error= \frac{|Predicted-value - Actual-value|}{Actual-value} \times 100 \%[/tex]
[tex]=\frac{|38-28|}{28} \times 100 \%[/tex]
[tex]=\frac{10}{28}\times 100 \%[/tex]
[tex]=35.71 \%[/tex]
Therefore, the percent error is [tex]35.71 \%[/tex]
