Two teachers from our class took 58 of our classmates to play in the amusement park on weekends. The amusement park stipulates that each adult ticket is 10 yuan, each student ticket is 6 yuan, and each group ticket (more than 50 people) is 7 yuan. How do you think about buying it? Is the ticket worth it? How much is the total?
