For this question, we only need the data at the Congtin column.
So, we have:


First, we need to reduce Giraffe by 63%.
This gives:




Represent this as a ratio:

The closest to this ratio is 3:7.
This is shown by dividing the ratio by 15
i.e.


Approximate:

Answer:
So F(x+3) = (x+3+5)/2 = (x+8)/2
Step-by-step explanation:
Given F(2x-1) = x+2
Put 2x-1 = y=> x = (y+1)/2
Hence F(y) = (y+1)/2 +2 = (y+5)/2
So F(x) = (x+5)/2
So F(x+3) = (x+3+5)/2 = (x+8)/2.
6n - 10 = 4n + 6
6n - 10 + 10 = 4n + 6 + 10
6n = 4n + 16
6n -4n = 4n - 4n + 16
2n = 16
2n/2 = 16/2
n = 8.
The solution is that the value of n = 8.
