In 2016,the population of the United States was approximately 325 million people,with an annual growth rate of approximately 0.7%.If the population of the U.S.were to continue to grow at this rate,the population of the U.S.would double around the year __________________

To calculate the number of years it takes for a population to double, we use the formula:

t = (ln 2) / r

where t is the time it takes to double, ln is the natural logarithm, and r is the annual growth rate in decimal form.

Plugging in the given values, we get:

t = (ln 2) / 0.007 ≈ 99 years

So, if the growth rate remains constant, the population of the U.S. would double in approximately 99 years from 2016. Adding 99 years to 2016, we get:

2016 + 99 = 2115

Therefore, the best choice is D) 2116, which is the closest year to 2115.
