\n" ); document.write( "Use the percentages to determine how many quarts are in the solution after the water has been evaporated; then use that to determine how much water needs to be evaporated.

\n" ); document.write( "\".65%2817%29+=+.85%28x%29\"

\n" ); document.write( "\"x+=+%28.65%2817%29%29%2F%28.85%29+=+%2865%2A17%29%2F%2885%29+=+65%2F5+=+13\"

\n" ); document.write( "There need to be 13 quarts in the final mixture for it to be 85% antifreeze; since there were 17 quarts at the start, 4 quarts were evaporated.
