Total: 112
Number of people who fish the salt water river: 98
People who do not feel that the amount of fresh water released should be reduced:
Total: 87
Number of people who fish the salt water river: 12
We can create a table to organize the information:
110 people fish the salt water river (98 + 12)
89 people do not fish the salt water river (14 + 75)
112 people feel that the amount of fresh water released should be reduced
87 people do not feel that the amount of fresh water released should be reduced
