The graph shows the growth rate of a certain bacteria in a lab, where the number of bacteria depends on the number of hours since the start of the experiment.

based on the graph, what is the approximate number of bacteria after 16 hours?
6 bacteria
8 bacteria
60 bacteria
80 bacteria

This doesn't make any sense. According to this graph you don't even reach 15 hours. I guess it would be whatever the largest value is. unless there is any other answer choices not listed

ANSWER

The approximate number of bacteria after 16 hours is


EXPLANATION

The values on the x-axis indicates the time.

Between 10 hours and 20 hours, there are 3 boxes.

This means that each box is

So can estimate 16 hours from the graph to be between the first and second box after 10 hours (see graph for the position).

We now trace to the y-axis to determine the corresponding number of bacteria.

This gives us the number of bacteria to be


The correct answer is C.

There is no question, there is just the answer.
