One way is that 16% is one-third of the way from 12% to 24%, so use 2/3 12% (600 pounds) and 1/3 24% (300 pounds)
\n" ); document.write( "x=12%
\n" ); document.write( "900-x=24%
\n" ); document.write( ".12x+.24(900-x)=900*.16
\n" ); document.write( ".12x+216-.24x=144
\n" ); document.write( "-.12x=-72
\n" ); document.write( "x=600 pounds
\n" ); document.write( "900-x=300 pounds
\n" ); document.write( " \n" ); document.write( "
\n" );
