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?
