The initial population was 80
<h3>
Solution ;</h3>
The bacteria culture has a constant growth rate.
So, N(t) = No*(1 + r)^t
Solution :
400 = No*(1 + r)^2
50000 = No*(1 + r)^8
(1 + r)^6 = 125
=> 1 + r = 2.2360
No = 400÷(1 + r)^2 = 80
Hence, now we can conclude that the initial number of the bacterial culture was 80.
