\n" ); document.write( "-------------
\n" ); document.write( "Let # of $4 pieces be \"x\"; value is 4x dollars
\n" ); document.write( "--------------
\n" ); document.write( "# of $8 pieces is \"120-x\" ; value is 8(120-x)=960-8x dollars
\n" ); document.write( "---------------
\n" ); document.write( "EQUATION:
\n" ); document.write( "value + value = 560 dollars
\n" ); document.write( "4x + 960-8x = 560
\n" ); document.write( "-4x = -400
\n" ); document.write( "x = 100 (# of $4 pieces)
\n" ); document.write( "120-x = 20 (# of $8 pieces)
\n" ); document.write( "==================
