b=2f
\n" ); document.write( "3.50b+4.50f=46.00
\n" ); document.write( "3.50*2f+4.50f=46.00
\n" ); document.write( "7.00f+4.50f=46.00
\n" ); document.write( "11.50f=46.00
\n" ); document.write( "f=46.00/11.50
\n" ); document.write( "f=4 boxes of felt tip pens were bought.
\n" ); document.write( "b=2*4=8 boxes of ball point pens were bought.
\n" ); document.write( "Proof:
\n" ); document.write( "3.50*8+4.50*4=46.00
\n" ); document.write( "28+18=46.00
