4-1 DMP/Answer

This is a problem I first saw in 1993 in Bill Davis' newsletter.  It was an article by Kit Woolsey.
In 1993 I got it wrong.  I recently came across this problem and this time, I got it right!  So maybe I have learned something?   Have you?

There's a quote I like:  "Does he have 20 years of experience, or one year of experience 20 times?"
