Answer:
a) 413 million
Step-by-step explanation:
To find the approximate population of the United States after 25 years, we can use the compound interest formula:
A = P(1 + r)^n
Where:
A = Final population
P = Initial population
r = Growth rate (expressed as a decimal)
n = Number of years
In this case, the initial population (P) is 300 million, the growth rate (r) is 2% or 0.02, and the number of years (n) is 25.
Plugging these values into the formula, we get:
A = 300 million * (1 + 0.02)^25
Calculating this, we find that the approximate population of the United States after 25 years is around 413 million.
Therefore, the correct answer is:
a) 413 million
