Question

4. A toy boat costs $45.25. If the sales tax in Maryland is 6%, what is the total you will need to pay for the

boat?

Answer 1

`\begin{array} \cline{1-1} \textit{a\% of b}\\ \cline{1-1} \\ \left( \cfrac{a}{100} \right)\cdot b \\\\ \cline{1-1} \end{array}~\hspace{5em}\stackrel{\textit{6\% of 45.25}}{\left( \cfrac{6}{100} \right)45.25}\implies 2.715~\hfill \underset{\textit{price plus tax}}{\stackrel{45.25+2.715}{\approx 47.97}}`
