11. (10 points) The cinema is screening four animated films: "Toy Story", "Ice Age", "Shrek", and "The Monkey King", with ticket prices of 50 yuan, 55 yuan, 60 yuan, and 65 yuan, respectively. Each audience member can watch at least one and at most two films. Due to time constraints, "Ice Age" and "Shrek" cannot both be watched. If there must be 200 people who spend the same amount of money on movies today, what is the minimum number of audience members the cinema will receive today?
【Analysis】According to the Pigeonhole Principle, the choices for the audience to spend money are: $50, 55, 60, 65, 105, 110, 115, 120$,
125, a total of 9 choices, so the number of audience members is $(200-1) \times 9+1$.
【Solution】According to the given conditions, we can get
(200-1) $\times 9+1=1792$ (people)
Answer: The cinema received at least 1792 people today.
