Answer: b. 30%
Step-by-step explanation:
We know that if the growth is exponential , then the growth factor is given by :-
[tex]G=(1+r)[/tex], where r is the rate of growth.
From the given table, the percent corresponding to the growth factor 1.30 is missing.
Now, substitute G = 1.30 in the above formula we get
[tex]1+r=1.30\\\\\Rightarrow\ r=1.30-1\\\\\Rightarrow r=0.30[/tex]
In percent, [tex]r=0.30\times100=30\%[/tex]
Hence, the missing value is 30%.
