The population growth formula is given by
[tex]P=P_o(1+r)^t[/tex]Where P₀ is the initial population, r is the growth rate in decimal, and t is the time in years.
P₀ = 324 million
r = 0.8% = 0.008
t = 2030 - 2016 = 14 years
Let us substitute these values into the above formula
[tex]\begin{gathered} P=P_o(1+r)^t \\ P=324_{}(1+0.008)^{14} \\ P=324_{}(1.008)^{14} \\ P=362\; \text{million} \end{gathered}[/tex]Therefore, the predicted U.S population in 2030 is 362 million
