Question

A family eats at a restaurant. The bill is $120. The family leaves a tip and spends $140. How much was the tip as a percentage of the bill? Round to the nearest tenth

Answer 1

ANSWER

$16.7\%$

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:

$\begin{gathered} \frac{20}{120}\cdot100 \\ \approx16.7\% \end{gathered}$

That is the answer to the nearest tenth.
