Hello,

I found this problem in one textbook and it's driving me nuts:

An instructor has two colleagues. One has three textbooks on analysis of algorithms, and the other has five such textbooks. If n denotes the maximum number of different books on this topic, then 5 <= n <= 8 is what can be borrowed from these two instructors.

My problem is, shouldn't it be 3 <= n <= 8?

Could somebody please explain to me why it is 5 <= n <= 8 if it's correct?

Thanks,

Victor.
