Keith modeled the growth over several hundred years of a tree population by estimating the number of the trees' pollen grains per square centimeter that were deposited each year within layers of a lake's sediment. He estimated there were 310 pollen grains per square centimeter the first year the grains were deposited, with a 1 % annual increase in the number of grains per square centimeter thereafter. Which of the following functions models P(t), the number of pollen grains per square centimeter t years after the first year the grains were deposited?

  1. A

    P(t)=310^t

  2. B

    P(t)=310^1.01 t

  3. C

    P(t)=310(0.99)^t

  4. D

    P(t)=310(1.01)^t
