A friend's daughter has a brain teaser for school each week. This week's is
9 = DP in the MW
Can you solve it?
previous brain teasers have been:
7 = D in the W (7 = days in the week)
13 = D in a BD (donuts in a bakers dozen)
24 = H in a D (24 hours in a day)
We have the entire legal dept. at work stumped by it, and my daughter at college has all of her friends stumped too,

I was hoping somebody here could help solve it! Thanks for anything you come up with.
