A certain species of fish has been declining in population by 7% per year. That means its rate of decay is 0.93. The population at time zero is 500,000.
What is the initial population?

0.93 ×500,000 is the I initiall population

Answer:

The initial population would be 500,000.

Step-by-step explanation:

Let P be the initial population that is declining in population by 7% per year,

So, the population after t years is,

[tex]A=P(1-\frac{7}{100})^t[/tex]

[tex]=P(1-0.07)^t[/tex]

[tex]=P(0.93)^t[/tex]

Since, if t = 0,

The population would be,

[tex]A=P(0.93)^0=P[/tex]

According to the question,

A = 500,000

Hence, the initial population would be 500,000.
