In a survey, 112 people feel that the amount of fresh water allowed to empty
into the salt water river should be reduced, and 87 people did not feel that
the amount of fresh water allowed to empty into the salt water river should
be reduced. Of those who feel that the amount of fresh water released should
be reduced, 98 people fish the salt water river. Of those that do not feel that
the amount of fresh water released should be reduced, 12 people fish the salt
water river.



Answer :

Let's break down the information:

Total people surveyed: 112 + 87 = 199

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
