Question

A culture started with 2,000 bacteria. After 7 hours, it grew to 2,600 bacteria. Predict how many bacteria will be present after 15 hours. Round your answer to the nearest whole number

Answer 1

Answer: Look at explanation for answer...

Explanation:

This could be turned into a simple proportion if you want to do it that way :)

1.) First, use the proportion bacteria over time.

2.) It should set up to look like this: 2,600 X

---------- = ---------

7 15

3.) You then do your math (2,600 * 15) (39,000 / 7)

Answer: Your answer then comes out to be: (rounded) 5,571 bacteria

Answer 2

the answer is 3,512. I just took the test and got the answer below me wrong. So, this should be what you are looking for.
