Two stark choices: a hardcore liberal arts curriculum vs. b-school. No one can offer you any true advice bcos these options are so different. IMO, it would not much matter if you were comparing a non-HYP Ivy math major to IU-biz.
Full tuition vs. sticker? A near no-brainer to me, but ONLY iff you want biz. (Personally, I'm not a fan of undergrad biz at the high level, but I'm probably in the minority.)
