Question

a population of 430 animals decreases at an annual rate of 21%. find the multiplier for the rate of exponential decay

Answer 1

P(t) = P0e-rt
where:
P(t) = the amount of some quantity at time t
P0 = initial amount at time t = 0
r = the decay rate
t = time (number of periods)

Initial amount (P0) = 430
Decay rate (r) = 0.23 = 23.0%
Time (t) = 1
