re: If you won $250 million powerball, how much would you give the HS you attended?

Absolutely nothing.

There's only one instance I'm donating to a school. I've always said if I was rich, I'd donate enough to the LSU Mechanical Engineering department. Two conditions; they change the building back to CEBA (dont know what they plan to call the new building so I dont know if this is even relavent anymore ), and fire one professor who taught a class that was not required at any other university from my understanding. He wrote the book, "taught" the class, and graded on opinion. I dont hate the guy, I'd pay him too so he wouldnt need money. But I think the program would be better without him and a good way to blow some money.
