Type the correct answer in the box. Round your answer to the nearest whole number.
The population in the United States in 2015 was 321 million people. It is projected to increase to 438 million people by the year 2050.
If projections are true, the US population will increase
% from 2015 to 2050.



Answer :

To determine the percentage increase in the US population from 2015 to 2050, follow these steps:

1. Determine the population increase:
- The population in 2015 is given as 321 million people.
- The projected population in 2050 is 438 million people.
- The increase in population is calculated by subtracting the 2015 population from the 2050 population:
[tex]\[ 438 \text{ million} - 321 \text{ million} = 117 \text{ million} \][/tex]

2. Calculate the percentage increase:
- To find the percentage increase, divide the increase in population by the population in 2015 and then multiply by 100:
[tex]\[ \left( \frac{117 \text{ million}}{321 \text{ million}} \right) \times 100 = 36.44859813084112\% \][/tex]

3. Round the result to the nearest whole number:
- The calculated percentage increase is approximately 36.45%.
- When rounded to the nearest whole number, this value is 36%.

Thus, the projected percentage increase in the US population from 2015 to 2050 is 36%.
