Many respected public universities cost less than that even at full price for non-residents.
@moooop gave several examples. You can find more here:

(sort on the column labelled “Total cost per year (out-of-state)”)
The most prestigious private universities cost more (about $60K-$70K).
Without knowing more about your family finances, one cannot tell if you would qualify for need-based financial aid. Run the online net price calculators for any college that interests you.
Try these for example:

These 5 are respected universities that have undergraduate business programs and are relatively generous with need-based aid (for qualifying US citizens, anyway.)
