Question

A culture started with 2,000 bacteria. After 6

hours, it grew to 2.200 bacteria. Predict how
many bacteria will be present after 12 hours
Round your answer to the nearest whole
number.

Answer 1

There will be 2.400 bacteria after 12 hours.
If it grew by 0.200 in 6 hours then it will be 0.400 at 12 hours because it is doubled.
