Irrigation of the crops led to salinization of the soil, Sumer was located on a flat plain that provided no natural barriers to invasion, and the land became to swampy to grow adequate crops.
You just follow the formula and see what it gets you from there.
The formula itself is literally b(1-r)t.
b= 2700
1 - 4% = .96
t = 5 years from 2015
This is a prediction, so it's exact value is irrelevant as long as it is close to your options, which Option C, 2202, is the best option for this.
I didn't follow the formula, however. I just did 10% of 2700, which is 270, and just multiplied it by 2, to get 20% of 2700 (Which is equal to 4% for five years decrease) and just subtracted the difference, leaving me with 2160, which is closer to 2202 rather than 2035. [Using the formula in the calculator kinda confused me, as it didn't turn out so pretty.]
