Question

What percent tip was given if a customer left$5 on a bill that had a subtotal of $31.25?

Answer 1

Let's begin by identifying key information given to us:

Bill = $31.25

Tip = $5

The percentage tip left is calculated as shown below:

`\begin{gathered} (tip)/(bill)\cdot100\text{\%} \\ (5)/(31.25)\cdot100\text{\%} \\ 0.16\cdot100\text{\%=16\%} \\ \Rightarrow16\text{\%} \end{gathered}`

Therefore, the percentage tip is 16%
