Question

Julia's service charge at the salon was $72.60. If she added 20% for tip, how much did she pay total for her service at the salon?

Answer 1

The answer here’s 72.60 or 14.52

Answer 2

well, is just that much plus the 20%, hmmm what's 20% of 72.60 anyway?

`\begin{array}c \cline{1-1} \textit{\textit{\LARGE a}\% of \textit{\LARGE b}}\\ \cline{1-1} \\ \left( \cfrac{\textit{\LARGE a}}{100} \right)\cdot \textit{\LARGE b} \\\\ \cline{1-1} \end{array}~\hspace{5em}\stackrel{\textit{20\% of 72.60}}{\left( \cfrac{20}{100} \right)72.60}\implies 14.52~\hfill \underset{total~pay}{\stackrel{72.60~~ + ~~14.52}{\text{\LARGE 87.12}}}`
