Answer 1

Answer:b

Step-by-step explanation:

Answer 2

Answer: B) 28% increase

======================================================

Step-by-step explanation:

There are 2 extra members because 9-7 = 2

Divide this change (2) over the original amount (7) to get the approximate value of 2/7 = 0.2857 which converts over to roughly 28.57%

That rounds to 29%, but that isn't listed. So I'd go with 28% instead. The estimate is close enough.
