Perhaps this is a different Olin school? (There are a number of universities with Olin schools or colleges on them.) The current cost of attending Olin before factoring in the half-tuition scholarship is $71,825 (see http://www.olin.edu/admission/costs/cost-of-attendance/). After including the half-tuition scholarship, which all students receive, costs drop to $47,525 per year. I'm not sure where an extra $100K in student loans would be coming from. Additionally, Olin provides need-based aid for those who qualify.
