ANSWER


16.7\%

Step-by-step explanation

We want to find the tip as a percentage of the bill.

First, let us find the tip. To do this, subtract the bill from the total the family spent.

That is:


\begin{gathered} 140-120 \\ \$20 \end{gathered}

Then, divide the tip by the bill and multiply by 100:


\begin{gathered} (20)/(120)\cdot100 \\ \approx16.7\% \end{gathered}

That is the answer to the nearest tenth.
