For the answer to the questions above,
A) Parrots are following a Geometric Progression of 15% increase.
20(1.15),  20(1.15)², 20(1.15)³,
Function  = 20(1.15)^n      Where n is at the end of year, n =1, 2, 3, ..
Snakes are increasing by 4.
28, 32, 36,....
Function =  24 + 4n          n = number of end year,      n =1, 2, 3,...
<span>B) After 10 years:              </span>
Parrot =  20(1.15)¹⁰    = 80.91115471
Snakes =  24 + 4(10) = 64
<span>C) After what time they are the same: </span>
We use trial and error:
Test:  n                             20(1.15^n)                        (24 + 4n)
          1                                    23                                   28
          2                                    26.45                              32
<span>          3                                    30.41                             36    </span>
          4                                    34.98                              40
          5                                    40.23                              44
          6                                    46.26                              48
          7                                    53.20                              52
          8                                    61.18                              56
          9                                    70.36                              60
After year 7, the Parrots increases far more.
<span>At year 7 they are roughly the same.</span>
        
             
        
        
        
I believe that the last one is true 
because the linear equations are 
y=ax+b
which means that the point of y-axis is on one side and the slope, point on x-axis and y-intercept are on the other side 
good luck
