Step-by-step explanation:
given that a bacteria culture initially contains cells and grows at a rate proportional to its size.
If P be the size then growth rate
where k is constant of proportionality
separate the variables as

If after 1 hour population is B (say)

then k = ln B - ln A
Using this
P(t) = 
b) P(e) = 
c) Rate of growth = 
Unless you give B value, d cannot be solved
