Answer 1

well, we know that Bridgette has 2500 bucks, now her dad gave her 20% of 3000, well heck, what's 20% of 3000 anyway?

`\begin{array}ll \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 3000}}{\left( \cfrac{20}{100} \right)3000}\implies 600~\hfill \underset{\textit{yeap, she has enough}}{\stackrel{2500~~ + ~~600}{\text{\LARGE 3100}}}`
