you should be able to use growth and decay formula \[y=Ae ^{kt}\]

y = total population after time t A = Starting population k = % rate of growth t = time in hours or years e = Eulers number

So for number 2 would the 0.98 just be 98%?

and for number one, 1.132 or 113.2%?

so if you start with 100 and it grows to 113.2 what is the growth..?
campbell_st
  • campbell_st
for number 2... you start with 100 and it declines to 98... so what did it decline by answer as a pergentage
