The population of fish increased from 370 to 420
i.e
Present value = 420
Past value = 370
over the months of March and April

Growth rate= [tex]\frac{Present value - Past value}{Past value}[/tex]
Now,
Substituting values in formula
Growth rate= [tex]\frac{420 - 370}{370}[/tex]
= [tex]\frac{50}{370}[/tex]
= 0.135 or 13.5%
