Question

an endangered species of fish is currently has a population of 168 individuals. of the population increase by three percent every year, how many individuals will there be in four years?​

Answer 1

To determine how many individuals there will be in four years, you can use the compound interest formula:

Future Population = Current Population * (1 + Growth Rate)^Number of Years

In this case:

Current Population = 168
Growth Rate = 3% = 0.03
Number of Years = 4

Now, plug these values into the formula:

Future Population = 168 * (1 + 0.03)^4

Future Population ≈ 168 * (1.03)^4
Future Population ≈ 168 * 1.1255
Future Population ≈ 189.1

After four years, there will be approximately 189 individuals in the endangered fish species population, assuming a constant growth rate of 3% per year. Since the number of individuals must be a whole number, you can round up or down to the nearest whole number, which would be 189 individuals.
