A.
32
B.
30.5
C.

D.
27

Answer 1

Well, what you would need to do is do 6+4*x. x being each answer choice.
So it would be 6+4*32, 6+4*30.5, 6+4*29, 6+4*27. Whichever one equals 122, is the answer.

Answer 2

let
y=height
x=number of days

y=6+4x

for y =122

122=6+4x ==> x=29

so it takes 29 days, the answer is C .
