5R + 2F = 39
\n" ); document.write( "3R + 6F = 57
\n" ); document.write( "Add
\n" ); document.write( "8R + 8F = 96
\n" ); document.write( ".
\n" ); document.write( "There is more than one possibility here. Let's assume whole numbers only.
\n" ); document.write( "Red could be a dollar. That makes foil 96-8/8 or 11 each.
\n" ); document.write( "If R = 2, then F = 10 (8*2) + (8*10) = 96
\n" ); document.write( "If R = 3, then F = 9 (8*3) + (8*4) = 96
\n" ); document.write( "If R = 4, then F = 8
\n" ); document.write( "R = 5, then F = 7
\n" ); document.write( "R = 6, then F = 6
\n" ); document.write( "R = 7, then F = 5
\n" ); document.write( "R = 8, then F = 4
\n" ); document.write( "R = 9, then F = 3
\n" ); document.write( "R = 10, then F = 2
\n" ); document.write( "R = 11, then F = 1
\n" ); document.write( "
\n" ); document.write( "
\n" );
