change = 1.1
2 3.2
change = 3.6
3 6.8
change = 0.5 ??? no rain
4 7.3
change = 3.9
5 11.2
change = 1.4
6 12.6
change = 0.8
7 13.4
change = 2.5
8 15.9
well the change is up and down depending on rainfall I suppose but I guess I would just average it since I ddo not see a clear trend
av change yr =(1.1+3.6+.5+3.9+1.4+.8+2.5)/7
= 1.97 call it 2
after 22 years = 2.1 + 21(2) =44.1
I would pick c
