The approximate predicted population of fish living in the lake in the year 2020 is; B: 800
We are told that the equation that describes the curve of best fit for the fish population (y) is;
y = 1500(0.9)^(z)
where z represent the
number of 10-year intervals since 1960.
The table started in the year 1960 and we want to find the population in the year 2020.
Number of years after 2020 is;
2020 - 1960 = 60 years
60 years is 6 decades
Thus;
y = 1500(0.9)⁶ = 797 ≈ 800
