Let's begin by identifying key information given to us:
Bill = $31.25
Tip = $5
The percentage tip left is calculated as shown below:
[tex]\begin{gathered} \frac{tip}{bill}\cdot100\text{\%} \\ \frac{5}{31.25}\cdot100\text{\%} \\ 0.16\cdot100\text{\%=16\%} \\ \Rightarrow16\text{\%} \end{gathered}[/tex]Therefore, the percentage tip is 16%
