There are n students in a biology class, and only 6 of them are seniors. If 7 juniors are added to the class, how many students in the class will not be seniors?

Answer

At first, there are n students in the class, and 6 of them are seniors. It follows that initially n minus 6 students are not seniors. If 7 juniors are added to the class, there will be n minus 6 + 7, or n + 1, students in the class who are not seniors.
