You can put this solution on YOUR website!
You're eqn will come up:
\n" ); document.write( "$Rental charge + ($Rate)(No. of miles driven) = $ Cost
\n" ); document.write( "Showing this in figures: $\"x=dollar%2Fmile\"$ , $\"C=cost\"$ in dollars
\n" ); document.write( "$25+ ($x/mile)(no. of miles driven) = $Cost
\n" ); document.write( "$25 +($x/mile)(320 miles)= $89 ------------------> eqn 1
\n" ); document.write( " $\"%28x%2Fcross%28mile%29%29%28320cross%28miles%29%29=89-25\"$
\n" ); document.write( " $\"x=64%2F320\"$
\n" ); document.write( "x=$0.20
\n" ); document.write( "There you go the rental car charge $0.20/mile driven plus $25 flat rate
\n" ); document.write( "In doubt? go back eqn 1:
\n" ); document.write( " $\"25%2B%280.20%2Fcross%28mile%29%29%28320cross%28miles%29%29=89\"$
\n" ); document.write( " $\"25%2B64=89\"$
\n" ); document.write( " $\"89=89\"$
\n" ); document.write( "Thank you,
\n" ); document.write( "Jojo \n" ); document.write( "
