Ответ:
2,482 fishes will be in the pond after 5 months
Step-by-step explanation:
First, let us model an equation that is used to determine the fish population after n months:
Let the initial population of the fishes = P₀
Let the population after n months = Pₙ
percentage increase each month = 7%
Next, we are told that 300 fishes are lost each month, therefore, the population after n months is given by:
Therefore population after 5 months:
n = 5
≈ 2,482 fishes
