5B+3V=27.50 MULTIPLY BY -2 & ADD.
\n" ); document.write( "2B+6V=23.00
\n" ); document.write( "-10B-6V=-55.00
\n" ); document.write( "-----------------
\n" ); document.write( "-8B=-32.00
\n" ); document.write( "B=-32.00/-8
\n" ); document.write( "B=$4.00 FOR EACH ROAST BEEF SANDWICH.
\n" ); document.write( "2*4.00+6V=23.00
\n" ); document.write( "8.00+6V=23.00
\n" ); document.write( "6V=23.00-8.00
\n" ); document.write( "6V=15.00
\n" ); document.write( "V=15.00/6
\n" ); document.write( "V=$2.50 FOR EACH VEGETARIAN SANDWICH.
\n" ); document.write( "PROOF:
\n" ); document.write( "5*4+3*2.50=27.50
\n" ); document.write( "20+7.50=27.50
\n" ); document.write( "27.50=27.50\r
\n" ); document.write( "\n" ); document.write( "
