Elis [28]

Answer:

246

Explanation:

Increased amount / current population = 972

Amount released = 108

time(t) = 2years

Using the exponential growth function :

f(t) = A*g^t

Where g = growth rate

To obtain the growth rate = g

972 = 108 * g^2

g^2 = 972 / 108

g^2 = 9

g = 3

To determine population after 9 months :

9 months to years = (9/12) = 0.75

t = 0.75

f(0.75) = 108*(3^0.75)

f(0.75) = 108 * 2.2795070

f(0.75) = 246.18676

= 246
