A colony of Salmonella bacteria

Question

has a current population of 1000

organisms. If this particular strain has

a doubling time, d, of 18 minutes,

calculate the future population after

180 minutes.

1000er^18
1e+54

Answer 1

It doubles ten times
t x
0 1000
18 2000 one time
36 4000 2 times
54 8000 3 times
72 16000 4 times or 1000*2^4
90
108
......
180 1024*1000 = 1,024,000 = 1000*2^10

Answer 2

You might want the equation:

number = 1000 (2^(t/18) )

so when t = 180
number = 1000 (2^10) = 1000(2^10) , the same result that Damon got

Answer 3

1024000?
