A certain plant was 11 feet long on the day it was plantedthe length grows by a constant amount everyday(inc. the first day it was planted).
if this plant grew by 30% b/w the 4th day and 10 th day after it was planted ,how many feet per day does the plant grow  Choose the correct option:
A) a) 2
B) b) 4.5
C) c) 0.69
D) d) 5.5
E) e) 3
If the plant is 11 feet tall when it is planted, it will be 11 + k feet tall at the end of the day (where k is the constant length it grows by every day).   Similarly, at the end of the 4th day the plant must be 11 + 4k feet tall and at the end of the 10th day it must be 11 + 10k feet tall.   Therefore 6k = 0.3 (11 + 4k)   =&gt; k = 0.69   Therefore the plant grows by 0.69 feet every day.   Option (c) 0.69)
