Show the basic formula this way:
\n" ); document.write( "\"A=+P+e%5E%28rt%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "You are looking for t when this occurs, for the question part: \"2=e%5E%28rt%29\"
\n" ); document.write( "-
\n" ); document.write( "\"ln%282%29=rt%2A1\"
\n" ); document.write( "\"highlight%28t=ln%282%29%2Fr%29\"------------formula for the doubling-time.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Use r=0.11 to find the correct value for t.
\n" ); document.write( "
\n" );
