To find out how many cookies the Cook family has left, let's break it down:

1. Let $x$ be the total number of bags of cookies they bought.
2. Each bag contains 16 cookies.
3. So, the total number of cookies they had is $16x$.
4. They've eaten 25 cookies, so the remaining cookies is $16x - 25$.

To find out exactly how many cookies they have left, we need to know how many bags of cookies they bought. Could you provide that information?
