\n" ); document.write( "~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "        Unfortunately, the problem missed to disclose a criterion, according to which it is determined\r
\n" ); document.write( "\n" ); document.write( "        that the balance is below $1,000. It can be the balance on the last day of a month, or, alternatively, \r
\n" ); document.write( "\n" ); document.write( "        the average balance per month.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "        But since the problem does not disclose a precise criterion, I will assume that the balance on the last day\r
\n" ); document.write( "\n" ); document.write( "        of the month is the criterion. It is very natural and very consistent with the problem to think so.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "        OK. Armed with this assumption, let' start the solution.\r
\n" ); document.write( "

\r\n" );
document.write( "Let's assume that the teacher withdrawals $290 on February, 25.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "So, the day 6 months later is August, 25,  and we should find out the teacher's balance on August, 25.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Let's make a timebook with balances, as shown below.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Feb.25  $1283.78 - $290 = $993.78.  At the end of February, $10 subtracted. The rest is  $983.78.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Mar.25.  No withdrawals.            At the end of Match,    $10 subtracted. The rest is  $973.78.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Apr.25.  No withdrawals.            At the end of April,    $10 subtracted. The rest is  $963.78.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "May 25.  No withdrawals.            At the end of May,      $10 subtracted. The rest is  $953.78.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "June 25. No withdrawals.            At the end of June,     $10 subtracted. The rest is  $943.78.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "July 25. No withdrawals.            At the end of July,     $10 subtracted. The rest is  $933.78.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Aug. 25. No withdrawals.            On August, 25, the teacher has  $933.78 at her account.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "ANSWER.  The teacher's balance 6 months later is $933.78.\r\n" );

\n" ); document.write( "\n" ); document.write( "I was taught as a child that it is bad manners to count money in someone else's pocket.
\n" ); document.write( "Especially when the other person is so reputable and respectful person as a teacher (my teacher !)
\n" ); document.write( "Therefore, I didn't even attempt to solve this problem.
\n" ); document.write( "But when I saw another tutor's incorrect solution, giving $923.78 as the answer,
\n" ); document.write( "I couldn't contain myself anymore. May my teachers forgive me . . . \r
