--------percent ---------------- quantity
\n" ); document.write( "fat milk 8 ---------------- 160 gallons
\n" ); document.write( "non fat milk 0 ---------------- x gallons
\n" ); document.write( "Mixture 2 ---------------- 160 + x gallons
\n" ); document.write( "
\n" ); document.write( "8*160+0x=2(160+ x)
\n" ); document.write( "1280 +0x=320 +2x
\n" ); document.write( "0x+-2x = 320 -1280
\n" ); document.write( "-2x = -960
\n" ); document.write( "/ -2
\n" ); document.write( "x = 480
\n" ); document.write( " 480 gallons of non fat milk
\n" ); document.write( "
