How many people at a given inner city school might order corsages? I'm writing about a florist making corsages by themselves because they haven't hired anyone yet, and I'm trying to figure out exactly what that workload might look like. In this scenario, the prom organizers contacted this florist to arrange for students to preorder corsages and boutonnieres via the school. (There's also another school in the area that just handed out business cards to the kids to order directly.)

If I can just get an estimation on the average student population of an inner city school in the US or Canada, I could figure it out from there. But any help on this subject would be helpful!

I was homeschooled, so I just don't have the first hand experience for any of this. Otherwise I'd just go with my best guess.
