I didn't get in to MIT, but if I had, it's unlikely I would have attended, due to financial reasons. I went to a state school, and had a handful of scholarships to help me out.
In retrospect, I would have been better off applying to UIUC, Purdue, or CMU, but quite a lot of the decisions I made when young would have turned out differently if I knew then what I know now.
I don't know when you applied but my understanding is that MIT http://news.mit.edu/2008/tuition-0307 this is from 2008 presumably that number has gone up (stanford is now free for families earning under 125k for instance)
It would have been around 1994 and 1995. Historic data say that my 4-year (sticker price) total would have been just a bit over $90k (equivalent to $133k in 2017 dollars) for tuition alone. I don't have the receipts, but I think my parents only had to pay about a quarter of that, including non-tuition expenses, to a markedly less prestigious school.
