Hello Brittanna , pls can u help me clear up some Maths doubts:

1)
Hello, pls can u have a look at this question :

question 6b from here
http://www.school-portal.co.uk/Group...urceId=3992068

I did in this method:

lnN = kt + c
then I did N= e^(kt +c)

N= e^kt *e^c
N= Ae^kt
But, then to find what A is:
N0= A*e^0
Therefore , A= N0.
then i subbed it back in to get N= N0e^kt

But then the mark scheme has got a different method on , pls can u have a look if i would get the marks :
