There are aproximately 330 million Americans. If the annual populaton growth rate is 1.005, what will the population bein 10 years?
Homework Answers
The growth of human population is given by-
Annual growth rate = (P2- P1) / (P1 x T) --- equation 1
Where, P2 = final population
P1 = Initial population ; [Given, P1= 330 x 106]
T = time (in year) accounted for population growth ; [Given, T= 10]
Annual growth rate = 1.005
Putting the values in equation 1
1.005 = (P2- 330 x 106) / (330 x 106 x 10) = (P2- 330 x 106) / (330 x 107)
Or, P2- 330 x 106 =1.005 x 330 x 107 = 331.65 x 107
Or, P2 = 331.65 x 107 + 330 x 106 = 331.65 x 107 + 33.0 x 107 = 364.65 x 107 = 3.65 x109
Hence, the population after 10 years will be 3.65 billion or 3646.5 million.
