Answer:
y = 67108864 rabbits
Step-by-step explanation:
The equation for growth is
y= a(b)^(t)
where a is the initial amount
b is the growth rate and
t is the time in months
2 years = 24 months
Assuming the population doubles at the end of the 1st month
Substituting in what we know
y = 4 (2) ^ (t)
y= 4 *2 ^ 24
y = 4*16777216
y = 67108864 rabbits
If they do not double at the end of the first month and wait until the second month, divide this number by 2
y = 4 (2) ^ (t-1)
y= 4 *2 ^ 23
y = 4*8388608
y = 33554432 rabbits
