Answer:
c) an entry fee be charged on summer weekend days when many people tend to visit the beach.
Step-by-step explanation:
Since Seymour's goal is to prevent overcrowding, then it is wise to require payment of an entry fee, on certain days when a lot of people tend visit the beach more. On other days when not so many people visit the beach, then there can be free entry for all who do.
This would be an efficient way to make sure the beach is not overcrowded.
