Question

Tommy and his friend ate at a restaurant and the total bill came out to $30, so they left a tip of $6.00. What percent did they leave?

Answer 1

They left 20% of the total bill as a tip

Here, we want to calculate the percentage of the bill they left as a tip

Mathematically, we have this as;

$\begin{gathered} \frac{tip}{\text{total bill}}\times100\text{ \%} \\ =\text{ }\frac{6}{30}\times\text{ 100 \%} \\ \\ =\text{ }\frac{100\text{ \%}}{5}\text{ = 20 \%} \end{gathered}$
