Question

Hanson's bill for lunch at a restaurant was $22. He left a 15% tip. What was the amount ofthe tip?

Answer 1

To find the amount of the tip we can use a rule of 3 when 22 represent the 100% so:

$\begin{gathered} 22\to100 \\ x\to15 \end{gathered}$

and the equation will be:

$\begin{gathered} x=\frac{22\cdot15}{100} \\ x=3.30 \end{gathered}$

So the tip was $3.30 dollars
