Answer 1

So first you divide 900 by 80 so that you know how many rooms there are. The answer is about 11.25. Then you multiply 11.25 by the number of principals, so that you know how many principals there are in total. 11.25 x 15 = about 169. This means the answer is that there were about 169 principals.
