There are 444 rats living in an old barn (yes, you counted them all). You get a cat, which is able to catch three rats per day. How many rats will be left after one month (let's say it's a 31-day month)?
351--except that the rats multiply at a rate of seven baby rats per day. Better get some more cats.
