13. Viviana!

i willgive medal

14. Viviana!

pleasseeeee

15. galacticwavesXX

what i am thinking you have to do is use the formula \[N(t)=N _{0}e^(kt)\] the problem is that we don't have anything in the data hat indicates time

16. galacticwavesXX

thats is e^kt idk why it came out like that

17. galacticwavesXX

are you sure you didnt leave out any givens that would help us?

18. Viviana!

let me see
