document.write( "The \"extra\" 8 sandwiches cost 8($2) = $16.<br><BR>\n" );
document.write( "The remaining items are equal numbers of sandwiches and floats, for a total of $156-$16 = $140.<br><BR>\n" );

document.write( "The number of sandwiches and floats that must be sold to make $140 is $140/$5 = 28.<br><BR>\n" );
document.write( "So the number of root beer floats sold was 28. (And the number of sandwiches sold was 28+8 = 36; but the problem didn't ask for that....).<br><BR>\n" );
