5x+2(480-x)=3*480
\n" ); document.write( "5x+960-2x=1440
\n" ); document.write( "3x=1440-960
\n" ); document.write( "3x=480
\n" ); document.write( "x=480/3
\n" ); document.write( "x=160 lbs. of %5 nuts is used.
\n" ); document.write( "480-160=320 lbs. of $2 mix is used.
\n" ); document.write( "Proof:
\n" ); document.write( "5*160+2*320=3*480
\n" ); document.write( "800+640=1440
