Question

A culture started with 1,000 bacteria. After 5 hours, it grew to 1,200 bacteria. Predict how many bacteria will be present after 11 hours. Round your answer to a whole number

Answer 1

N=b*g^t
b=1000,
1200=1000*g^5
g=1.03713729

So:
N=1000*1.03713729^t
After 11 hours:

N=1000*1.03713729^11 = 1 493.47771

So I'd say 1500.

Answer 2

1000 * (e^((1 /5) * ln(12/10) * (11))) = 1,493.5
