In 2001, the moose population in a park was measured to be 4,160. By 2009, the population was measured again and was found to be 5,040. Assume the population continues to change linearly.

Question

(a) Find a formula for the moose population, P, since 2001. (Let t represent the number of years since 2001.)

P(t) = 

(b) What does your model predict the moose population to be in 2017?

 moose

Answer 1

5040-4160 = 880 increase for 8 years, or 110 per year

P(t) = 4160 + 110(t)

P(16) = 4160 + 110(16) = 5920 moose
