Answer:

2011

Step-by-step explanation:

Here is the formula.

[tex]A=P(1+r)^{n}[/tex]

A = Final Value

P = Starting Value

R = Rate

N = Time in Years

A = 8,000,000,000

P = 5,400,000,000

R = 0.0195

N = Time in Years

Solve for n.

20.35 Years from 1990; so sometime in 2011 the population would be 8 billion.
