Question

There are 300 fish in a pond. The fish population is increasing by approximately 15% per year.

Enter an equation that can be used to find the amount of fish in the pond, y, after 6 years.
y= ?

Answer 1

To calculate the fish population after 6 years with a 15% annual growth rate from an initial population of 300 fish, use the exponential growth formula y = 300(1 + 0.15)^6.

Step-by-step explanation:

To find the number of fish in a pond, y, after 6 years given an initial population of 300 fish and an annual increase of 15%, you can use the formula for exponential growth. The equation is:

y = P(1 + r)^t

Where:

• P is the initial population.
• r is the growth rate (as a decimal).
• t is the number of years.

Using the values provided:

P = 300

r = 0.15

t = 6

The equation becomes:

y = 300(1 + 0.15)^6
