You can put this solution on YOUR website!
(cost of milk)/(gallon) x (gallons/month) = (cost of milk)/(month)
\n" ); document.write( " $\"%283%2F1%29%2A12+=+Y\"$
\n" ); document.write( " $\"Y+=+36\"$ dollars/month
\n" ); document.write( " $\"3X=+36\"$
\n" ); document.write( " $\"X+=+12\"$ gallons/month
\n" ); document.write( "I'm not sure why equations are needed
\n" ); document.write( " \n" ); document.write( "
