The Math of Farewells

Ending days at any job are often (always?) traumatic, even if you're leaving of your own free will to "pursue other interests". Today we have a sad departure - one of our folks is leaving us and ending employment at The Mighty Ansmar Publishers, home of Excel Math.

I'm going to make this departure a math problem, to give you an example of the sorts of things that kids learn using our elementary math curriculum.

Here are the rules.

1. I will provide the number of calendar days that have elapsed since the 10 people on the list below STARTED working at Ansmar. I call this the Job Duration Number (JDN).

2. Once you have seen the number of days, I will give you a math problem to solve, which will reveal the person who is leaving.

3. It's up to you to determine who will be a former employee at 4:30 this afternoon,

4. And who is the newly-hired replacement.



6280 Brad
6070 Dave
5410 Becky
5125 Bob
4700 Jim
2660 Mike
2000 Carmen
0950 Nick
0920 Darcie
0005 Lavonne

Whose job duration number consists of an odd number of hundreds with zero tens and zero ones? _______

Take that number and subtract 100. _______

Take the resulting total and use it as the dividend in a division problem. Use as your divisor the  job duration number of our most-recently hired employee. The quotient is the number of the person leaving today.

Who is leaving?  ___________

and who is the most-recently hired person? ____________
