The customer's bill before the discount is $1600.
The customer's bill after the discount is $1460.
Determine the discount on the customer's bill.
[tex]\begin{gathered} D=1600-1460 \\ =140 \end{gathered}[/tex]The discount is applied on the customer's bill before the discount. Let the percent discount is d%.
Determine the discount percent on the customer bill.
[tex]\begin{gathered} \frac{d}{100}\cdot1600=140 \\ d\cdot16=140 \\ d=\frac{140}{16} \\ =8.75 \\ \approx8.8 \end{gathered}[/tex]So percent discount is 8.8%.
