A worked illustrative example in the brief, assuming $100,000 salaries and benefits and a 25-student class size limit: with enrollment falling "from 75 students to 52 students," each teacher costs $5,769, "a 44 percent increase," because all three classrooms must be maintained.

"if a school’s 1st grade enrollment declines from 75 students to 52 students, then each teacher will cost $5,769—a 44 percent increase—because class size limits require that the school maintain all three classrooms."
