The growth rate of a population is the rate at which the population changes

The rate of change is 0.0729 people per second

Let:

b represents birth

d represents death

m represents migrant

So, the given parameters are:

[tex]\mathbf{b = \frac 18\ people/sec}[/tex]

[tex]\mathbf{d = -\frac 1{12}\ people/sec}[/tex]

[tex]\mathbf{m = \frac 1{32}\ people/sec}[/tex]

The negative sign represents death

So, the population change f'(o) every second is:

[tex]\mathbf{f'(o) = b + d + m}[/tex]

This gives

[tex]\mathbf{f'(o) = \frac 18 - \frac{1}{12} + \frac 1{32}}[/tex]

Take LCM

[tex]\mathbf{f'(o) = \frac{12 - 8 + 3}{96}}[/tex]

[tex]\mathbf{f'(o) = \frac{7}{96}}[/tex]

Divide

[tex]\mathbf{f'(o) = 0.072916}[/tex]

Approximate

[tex]\mathbf{f'(o) = 0.0729}[/tex]

Hence, the rate of change is 0.0729 people per second
