Problem 5- Raccoons, Purple Martins, and Mosquitos: The recent opening of a landfill in the area has caused the raccoon population to flourish, with an adverse effect on the number of purple martins (a type of bird). Wildlife specialists believe the population of purple martins p will decrease as the population of raccoons, r, grows. The relationship between these two populations is represented by the equation below: p(r) = 750 3.75r Mosquitoes are the primary diet of purple martins. Thus, the mosquito population m is a function of the population of purple martins p and is represented by this equation: m(p) 50,000- 45p 1 If there were no raccoons in the area before the land fill opened, then how many mosquitos are in the area at that time? a. b. If there were 200 raccoons in the area six months after the landfill opened, then how many mosquitos are in the area at that time? If there were r raccoons in the area one year after the land fill opened, then how many mosquitos are in the area at that time? c. d. If we don't want more than 36,500 mosquitos, then what should the raccoon population be? p. 20

Problem 5- Raccoons, Purple Martins, and Mosquitos: The recent opening of a landfill in
the area has caused the raccoon population to flourish, with an adverse effect on the number of
purple martins (a type of bird). Wildlife specialists believe the population of purple martins p
will decrease as the population of raccoons, r, grows. The relationship between these two
populations is represented by the equation below:
p(r) = 750 3.75r
Mosquitoes are the primary diet of purple martins. Thus, the mosquito population m is a function
of the population of purple martins p and is represented by this equation:
m(p) 50,000- 45p
