Question 802106: A population has size 15 at time t = 0, with t measured in years.
If the population grows by 9 people per year, find a formula for the population, P, at time t.
P =
If the population grows by 9% per year, find a formula for the population, Q, at time t.
Q =
Help is really appreciated.

The question about P is simply a linear relationship. The question about Q is more interesting, being exponential growth.

Helping for Q:

Time 0, Q=15.
Time 1, Q=15*1.09
Time 2, Q=15*1.09*1.09
.
.
and the pattern will be for time t,______________ highlight%28Q=15%2A%281.09%29%5Et%29
