You are fishing for surfperch and rockfish, which are species of bottom fish. Gaming laws allow you to catch no more than 15 surfperch per day, no more than 10 rockfish per day, and no more than 20 total bottom fish per day. Write a system of linear inequalities that represent the situation. Let X represent the number of surfperch and why represent the number of rockfish.
