Question

The world population is projected to be 8.2 billion in 2045. At that time, there are expected to be approximately 3 billion more people in Asia than in Africa. The population for the rest of the world will be approximately 0.2 billion more than half the population of Asia. Find the projected populations of Asia, Africa, and the rest of the world in 2045.
The projected population of Asia will be approximately billion

Answer 1

Answer:

Since the total population will be 9.4B people

W + A+ A =9.4B

W = 0.6B + A/4  

A+ 2.9B = As

A - 2.9B + As + 0.6 + A/4 = 9.4B

(9/4)*A= 11.7B

A = (4/9)*11.7B=5.2B

W = 0.6B + (5.2B/4) = 1.9B

A = 5.2B - 2.9B = 2.3B
