Now, Dan wants to keep the school open from $7$:$00$ AM until $10$:$00$ PM$.$ Dan's driving instructors, many of them school teachers, are angry because the changed hours will interfere with their teaching jobs. Dan's business depends on these teachers because they are the only people patient enough to deal with inexperienced drivers.
