Answer:
16 months for it to grow 8 inches
16
Step-by-step explanation:
growth in 1 month = 1/2 inches
growth in x months = x*1/2 inches
total growth = 8 inches
thus,
8 = x*1/2
x = 8 / (1/2)
= 16
x= - 1.48 or 0.48
I used general formula. Hope I'm on a right path.
the missing section is 49%
11 + 18 + 15 + 7= 51
51 + 49 = 100
add the percentages together and you get 100%

(11+21)-(3-101)=(11+21-3-10=(11-3)+(21-101=8-18=53
