Chris starts a fishing club with one friend. During week 2 the club has 4 members. The club membership over 5 weeks is shown in the table. If the pattern continues, how many members will be in the fishing club after 7 weeks?
Week Total
1 2
2 4
3 6
4 8
5 10
___________
A) 12 members
B) 14 members
C) 16 members
D) 18 members
B) 14 members. The rate of change is 2. To find the rate of change you should try y over x. So, Total over Weeks. Example: 10/5, simplified is 2. You can also find y, by doing x times rate of change. Therefore, 7 times 2, equals 14 members.
The answer is 14 Because for each week it goes up by 2. For example: 4/2 equals 2. 6/2 equals 2. For for every week you would divide by 2 since they all increase by two and that would be your answer.
