linear functions

Question

In 1994, the moose population in a park was measured to be 3870. By 1999, the population was measured again to be 4020. If the population continues to change linearly:

Find a formula for the moose population, , in terms of , the years since 1990.

Then:

Answer 1

Moose population = 3870 + 30t

4020-3870= 150

150/5 years = 30 new moose per year
