In a controlled breeding program at Melbourne Zoo, the

Question

population (P) of koalas at t years is modeled by
P = P_0 * 10^(kt). Given P_0 = 20 and k = 0.3:
a. calculate the number of koalas after 2 years
b. determine when the population will be equal to 1000

Answer 1

(a) just plug in your numbers
(b) just solve 20*10^(0.3t) = 1000

Answer 2
