When the birth rate is equal to each woman producing exactly enough offspring to replace herself and her offspring's father, and the birth rate is sustained for a generation, then .

Explanation:

When the birth rate is equal to each woman producing exactly enough offspring to replace herself and her offspring's father, and the birth rate is sustained for a generation, then there will be no increase in population so the net population growth will be zero.

Population of species is defined as the number of individuals of a given species.

For example, if their were 50 individuals in a population and a woman out of them mates with a man and produces one offspring to replace her and one offspring to replace her offspring's father, and then both of them die.

So the intrinsic rate of population growth = No. of birth -no. of death

a = p(1 + rt) . . account balance after time t at rate r starting with principal p

3000 = 2500(1 + 0.0202t) . . filling in the given numbers

1.2 = 1 + 0.0202t . . divide by 2500

0.2 = 0.0202t . . . subtract 1

0.2/0.0202 = t ≈ 9.901

it will take about 9.9 years for the account balance to reach $3000.
