That's not really true. Duke includes finical aid as a cost but that's not actual spending. So from the chart, 10/.76 = ~13% is administrative costs.
Though the Text says out of 90k in spending $14,000 goes to pay a share of administrative and academic support salaries which puts just salary's for administration at 15.5 not including their share of the building etc.
So, a reasonable estimate ~25-40% of each dollar actually spent goes to administration depending on where you draw the line. AKA is a dean Administration or Faculty.
PS: Not that facility get to actually spend anywhere close to 100% of there time on teaching.
