\bf \qquad \qquad \textit{inverse proportional variation}&#10;\\\\&#10;\textit{\underline{y} varies inversely with \underline{x}}\qquad \qquad  y=\cfrac{k}{x}\impliedby &#10;\begin{array}{llll}&#10;k=constant\ of\\&#10;\qquad  variation&#10;\end{array}\\\\&#10;-------------------------------

\bf (\stackrel{x}{8},\stackrel{y}{1})\textit{ we know that }&#10;\begin{cases}&#10;x=8\\&#10;y=1&#10;\end{cases}\implies 1=\cfrac{k}{8}\implies 8=k&#10;\\\\\\&#10;therefore\qquad \boxed{y=\cfrac{8}{x}}&#10;\\\\\\&#10;(x,\stackrel{y}{3})\textit{ when y = 3, what is \underline{x}?}\qquad 3=\cfrac{8}{x}\implies x=\cfrac{8}{3}

Before the mechanic worked on it, it cost .09 (cents) per mile.  After the mechanic worked on it, it cost .08 (cents) per mile.  Divide the number of gallons by the miles in each case and multiply the result by 4.
