After the last ice age began, the number of
animal species in Australia changed rapidly.
The relationship between the elapsed time, t,
in years, since the ice age began, and the total
number of animal species, Syear(t), is modeled
by the following function:
Syear (t) = 25,000,000 - (0.78)
Complete the following sentence about the
rate of change in the number of species in
decades.
Round your answer to two decimal places.
Every decade, the number of species decays
by a factor of
