Question

Ethan got a quote for labor that was 20% less than his budget amount. How much did he save on labor?

Answer 1

well, he had from his budget from the picture above $8950, now the quote he's got was 20% less than that, hmmm so he saved 20% of 8950, so how much is that anyway?

`\begin{array} \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 8950}}{\left( \cfrac{20}{100} \right)8950}\implies \text{\LARGE 1790}`
