Question

the 2020 census found a u.s. population of about 330 million. starting from this value, use the current u.s. annual growth rate of 0.6% (which includes immigration as well as births and deaths) to estimate u.s. population in 2048 and 2099. use the approximate doubling time formula.

what is the predicted population in 2048?
390 million
(round to the nearest whole number as needed.)

what is the predicted population in 2099?
million
(round to the nearest whole number as needed.)

Explanation:

Calculate the doubling time

Using the Doubling Time and Rule of 70 knowledge points

$$ T_{\text{double}} \approx \frac{70}{r} = \frac{70}{0.6} \approx 116.67\text{ years} $$
