Question

A pair of shoes that were $25 were marked up 30% by the store. How much will they cost?

Answer 1

`\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{30\% of 25}}{\left( \cfrac{30}{100} \right)25}\implies 7.5\hspace{5em}\underset{ \textit{marked up price} }{\stackrel{25~~ + ~~7.5 }{\text{\LARGE 32.5}}}`
