[TERMINATOR]

i think i posted a reply in the last few pages.

Really? Ok let me check it out, thank u

 

[TERMINATOR]

the one that is quoted in his question
the equationi formed in the first part is
y=e^15(e^(-2t))+ln70)
now we know the inital mass is 70 so
p=(the long equation quoted above/70)*100
as t==> infinity p==> 1 there u go

How do we get 100/e ? (ans)
