100% + 1.8% = 101.8%
101.8% = 101.8/100 = 1.018
1) 450 * 1.018 = 458.10 in one month
2) 458,1 * 1.018 ≈ 466.35 in two months
3) 466,35 * 1.018 ≈ 474.74 in three months
4) 474,74 * 1.018 ≈ 483.29 in four months

Answer: D.
N=8
If you set 2/3 equal to n/12 then you multiple 3 by 4 to get 12. So you have to multiple 2 by 4 to get N.
It would be called an ecological model.
The answer would be -0.102564 repeating because if you do the math before dividing you would get -8/6.5/-1.5/-8
