Question

Dear Mitch,

Can you hold off until tomorrow to post the answer to the 'Early Christmas' balance scale problem, because my students are still working on it and I'd like to present the answer later this afternoon before they have a chance to log into your site and get it themselves (I know that several students look at your site during their lunch period, and they've caught on to the fact that I get a lot of my most challenging questions from it).

Thank you,

Ms. Mitchell

Answer

Dear Ms. Mitchell,

Sure!

I'll post it either very late tonight or very early tomorrow morning!

(Usually I try to stick to whatever plan I put in place initially, but we have received a number of letters requesting the same thing as you:  more time before we unveil the mystery to that balance scale question.)

Thank you for your interest, and good luck to you and your class in arriving at your solution.

Tomorrow, when the answer is posted, all mystery should be gone!

Hope you continue to enjoy working towards the solution,

Mitch
