Landscaping Trees

RAY: What the little girl finds on her paper is something that you often find on graded papers from your third-grade teacher. At the top of the page is a star.

TOM: I never got one.

RAY: Oh. That's why you didn't get the answer to this either, you dumbo. And if you draw a five-pointed star, just like your third-grade teacher put on your papers, and you put a tree at every intersection point and a tree at every vertex...

TOM: You end up with four.

RAY: You end up with 10 trees, right?

TOM: Four, four, four.

RAY: Five rows of four trees each.

TOM: Whew!

RAY: Pretty good, hunh?

TOM: That is good!

RAY : Do we have a winner?

TOM: Yes, we do. Just a minute.

RAY: We always have a winner.

TOM: It looks like Catherine LaFeriere from Highland, Maryland.
