NYU would be 70K. Run the NPC. It’s likely to be unaffordable because they don’t meet need.
You can’t just “pay quite a bit”. You’re allowed $5,500 in loans for freshman year. Everything else comes from the university or your parents. Institutional aid (money from the college you applied to) is the #1 source of scholarships.
HOWEVER, if you want to study in a big city, you have lots of good options. Your stats are good and you can probably get to 31, perhaps 32 on your ACT, and you’re lucky to be living in WI which is rural in many places (it helps for some universities to come from a rural, public HS) and has a reciprocity agreement with Minnesota.
So, for a terrific business school in a big city, you have Carlson at U of M and if you have a serious shot at Honors College. You also have Macalester, of course, which is excellent for economics and anything international, with access to the Twin Cities for internships.
In NYC, you have Baruch (apply by Dec 1st to Macaulay) and Fordham. Run the NPC on Fordham.
In other big cities: Rhodes, Simmons, Northeastern, Boston College, WPI, UPitt, USC, SDSU, Lewis&Clark, UPortland, USeattle, DePaul, Loyola Chicago, Northwestern, UMiami, FIU Honors, USF (Florida), Case Western Reserve, Davidson, NCSU, Saint Louis University, American University, Georgetown, Wellesley, Barnard, Agnes Scott.
NEAR big cities (close enough to go on weekends), you have Bowdoin, Goucher, Ursinus, St Olaf, Dickinson, Bryn Mawr.
