0.16x+0.1(15-x)=0.12(15)
\n" ); document.write( "0.16x+1.5-0.1x=1.8
\n" ); document.write( "0.06x=0.3
\n" ); document.write( "x=5\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "15-5=10\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Hence, for 16% it is 50lb and for 10% it is 10-lb.
