Answer:
The population of mosquitoes in the area at any time <em>t</em> is:
Step-by-step explanation:
The rate of growth of mosquitoes can be expressed as:
Integrate the above expression as follows:
It is provided that the population doubles every day.
Compute the value of <em>k</em> as follows:
It is also provided that every day 20,000 mosquitoes are eaten.
The rate of growth per week can be expressed as:
The integrating factor for this is:
Then,
The initial population is 200,000.
Compute the value of <em>C</em> as follows:
Now substitute <em>C</em> in P (t),
