The original amount of silt was,
\n" ); document.write( " $\"5%2810%2F100%29=50%2F100=0.5\"$ $\"ft%5E3\"$
\n" ); document.write( "Now there is,
\n" ); document.write( " $\"0.5%2B1=1.5\"$ $\"ft%5E3\"$ of silt
\n" ); document.write( "And there is a total of $\"5%2B1=6\"$ mixture.
\n" ); document.write( "So the new concentration is,
\n" ); document.write( " $\"C=%28%283%2F2%29%2F6%29%2A100\"$
\n" ); document.write( "Work that out for the answer.
