The equation you need is a simple one.\r
\n" ); document.write( "\n" ); document.write( "Let the amount to be drained and replaced by 100% antifreeze be D
\n" ); document.write( "We then get the following equation: \"highlight_green%28highlight%28.2%2815+-+D%29+%2B+D+=+.5%2815%29%29%29\"
\n" ); document.write( "Solve for D, the amount to be drained and replaced.
\n" ); document.write( "It's that simple...nothing complex!! \n" ); document.write( "
