Aculture started with 1,000 bacteria. after 2 hours, it grew to 1,100 bacteria. predict how many bacteria will be present after 9 hours.

450 Bacteria

Step-by-step explanation:

First we need to consider the amount of bacteria that grew after two hours. Since 100 bacteria grew after 2 hours, we need to find how much bacteria grows per hour.

We can find that by dividing 100 by 2

100/2 = 50 Bacteria per hour

Now that we know how much bacteria grows per hour, we can then multiply that amount to the amount of hours asked in the problem.

9 hours x 50 Bacteria = 450 Bacteria in 9 hours.
