Organization A starts with 1050 members. Let's say it increases by x members per year. At the end of five years, the new number of members will be 1050 + 5xash4gmat wrote:Can some one help explain this URL

Organization B starts with 1550 members. Let's say it increases by y members per year. At the end of five years, the new number of members will be 1550 + 5y
We want those values to be equal. So
1050 + 5x = 1550 + 5y
5x - 5y = 500
x - y = 100
So we need the difference between the two values to be 100. The only option that would allow this would be if x = 130 and y = 30.

If we look at the table provided, it identifies the "rate" of increase as an increase in "members per year." So one rate of increase is 30 members/year and another rate of increase is 130 members/year.ash4gmat wrote:David,
I think question mentions an increase in no's at constant rate. For eg 10% every year on 1550 or 5 % on 1050.
My understanding is wrong?
