There are limited amounts of resources in a general area. Some civilizations may not have the ability to produce resources that they need. That makes 2 routes:
1) cooperation: They can cooperate with another people group that lives in a different region and trade with them
2) conflict: They can attack/raid another people group in a different region for the resources

Set this up as
10 = 40 (1/2)t/28
and solve for t in years.
10/40 = (1/2)t/28
log(0.25) = (t/28) log(0.5)
t = 28 log(0.25) / log(0.5) years = 56 years
Test the answer:
56 years = 2(28 years) = 2 half-lives, so the remaining amount should be 1/2 of 1/2 of the initial amount, i.e. 1/4 of the initial amount, and 10 mg = 1/4 of 40 mg.

Answer:
A total number of people within a continent
Explanation:
The population growth in a particular place is reflective of how the population is changing positively over a period of time.
It is simply the change in population with with time.
- The total population through a given time frame and within a geography is very important for population studies.
- The population growth formula is given as:
P = P₀ eᵇⁿ
P is the total population
P₀ is the starting population
b is the growth rate
n is the time
