Answer: The dolphin's population growth is 150% .
Explanation:
The birth rate of dolphins = [tex]2.0=\frac{2.0\times 100}{100}=200\%[/tex]
The death rate of the dolphins = [tex]0.5=\frac{0.5\times 100}{100}=50\%[/tex]
Dolphin's population growth = Birth rate - Death rate
= [tex]200\%-50\%=150\%[/tex]
The dolphin's population growth is 150%.
