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%.
