Joe spent $35.40 to fill 15 gallons of gas in his minivan. How much would 6 gallons of gas cost?

\begin{array}{ccll} \$&gallons\\ \cline{1-2} 35.40 & 15\\ x& 6 \end{array} \implies \cfrac{35.40}{x}~~=~~\cfrac{15}{6} \\\\\\ \cfrac{35.4}{x}=\cfrac{5}{2}\implies 70.8=5x\implies \cfrac{70.8}{5}=x\implies 14.16=x
