A petri dish originally contained 1,163 bacteria. A scientist let the bacteria grow and now there are 2,683 of them. How many more bacteria are there now?

Answer 1

To find out how many more bacteria there are now, we subtract the original number of bacteria from the current number of bacteria.

Starting with the original count of bacteria:

• Original count: 1,163
• Current count: 2,683

Now we perform the subtraction: \[ 2,683 - 1,163 = 1,520 \]

Therefore, there are 1,520 more bacteria now.
