\n" ); document.write( "The amount of salt is 12% of 80 pounds, which is 9.6 pounds.

\n" ); document.write( "You want those 9.6 pounds to be 20% of the final solution:

\n" ); document.write( " $\"9.6+=+.20%28x%29\"$
\n" ); document.write( " $\"x+=+9.6%2F.20+=+48\"$

\n" ); document.write( "The final solution needs to be 48 pounds; it originally was 80 pounds, so 32 pounds of water needs to be evaporated.

\n" ); document.write( " \n" ); document.write( "

\n" );
