You can put this solution on YOUR website!
Let x = cost of the ice cream.
\n" ); document.write( ".05x = tax on the ice cream.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Total cost = cost of ice cream + tax = $3.15
\n" ); document.write( "x + .05x = $3.15
\n" ); document.write( "1.05x = 3.15\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Divide each side by 1.05:
\n" ); document.write( "\"%281.05x%29%2F1.05+=+3.15%2F1.05+\"
\n" ); document.write( "x= $3.00 even!\r
