There are 44, 41, and 34 students in the three classes respectively. They chartered a car to go to the spring outing. It was stipulated that one of the three classes would take a large car, one class would take a medium car, and the other class would take a small car. To accommodate 7, 6, and 5 students, each car costs 80, 70, and 60 yuan, so how much is the minimum fare for these three classes?
