Interogate is just another term for, question, in much the same way that abandon is another word for quit. We all have the choice of answering, whether the stronger form of, interogate , or just, question. It is still a cheek to ask this question.
I'm a high school teacher in the states, and our salaries are set by a number of factors including education and experience. Based on those (6 years plus a Masters degree and 32 additional graduate credits), my contract salary is approximately $66,000 a year. In five or six years, that will grow to $70,000 or $80,000. It pays well to be a teacher, at least in my state (New Jersey) and with my degree of education.
