Question

A culture started with 6,000 bacteria. After 6

hours, it grew to 7,200 bacteria, Predict how
many bacteria will be present after 17 hours,
Round your answer to the nearest whole
number.

Answer 1

9,400 bacteria at Hour 17.

Explanation:

If at

Hour 0, it was at 6,000 bacteria then at

Hour 6, it would be at 7,200 bacteria

That means in 6 hours, the bacteria has grown by 1,200

Let's use a ratio:

hours : bacteria

6 : 1,200

1 : 200

17 : 3,400

Now after 17 hours, 3,400 new bacteria has joined our group of 6,000

6000+3400=9400

9,400 bacteria should be present at Hour 17
