To the nearest thousand people, what is the projected population 30 years from now?

Answer
A
214 comma 000 people
B
46 comma 000 people
C
143 comma 000 people
D
55 comma 000 people

Explanation

Substitute x = 30 into the model: y = 214 / (1 + 16.4e^(-0.05 × 30)) = 214 / (1 + 16.4e^(-1.5)) ≈ 45.9. Since y is measured in thousands of people, this is about 45,900 people, which rounds to 46,000 people. The correct choice is 46,000 people.
