Assume x lbs of 10% solution is mixed with (5 - x) lbs of 18% solution.\r
\n" ); document.write( "\n" ); document.write( "(0.1x + 0.18(5 -x))/5 = 0.12\r
\n" ); document.write( "\n" ); document.write( "-0.08x + 0.9 = 0.6\r
\n" ); document.write( "\n" ); document.write( "x = 3.75 lbs
\n" ); document.write( "
