Please see the attached file.

Let define the population birth rate as and the unit is births per person per year. Here =2% or 0.02

Let us define the population death rate as and the unit is deaths per person per year. Here =1.3% or 0.013

If the population at time t is N(t), then the number of births will be N(t).

1. If N(t)=8,000,000 then the rate of births is:

2. At the same year the ...
