You are fishing in a marina for surfperch and rockfish, which are two species of bottomfish. Gaming laws in the marina allow you to catch no more than 15 surfperch per day, no more than 10 rockfish per day, and no more than 15 total bottomfish per day. How many inequalities would you need to model this system of inequalities?

Could catching 11 surfperch and 9 rockfish in one day work for this model?
