Let's say the bed and breakfast charges X per night.
\n" ); document.write( "With 8% tax, it's $172.80.
\n" ); document.write( "Room Charge + Tax = Total
\n" ); document.write( " $\"X+%2B+8X%2F100+=+172.80\"$
\n" ); document.write( " $\"X+%2B+.08X+=+172.80\"$
\n" ); document.write( " $\"1.08X+=+172.80\"$
\n" ); document.write( " $\"X+=+172.80%2F1.08\"$
\n" ); document.write( " $\"X+=+160.00\"$
\n" ); document.write( "The room rate is $160.00 and the tax is ($160)(0.08) or $12.80.
\n" ); document.write( " \n" ); document.write( "
