To find the total number of cells in the three petri dishes, we need to add the number of cells in each dish:
- First dish: 22,340 cells
- Second dish: 43,560 cells
- Third dish: 36,612 cells
Now, let's calculate the total:
\[ 22,340 + 43,560 + 36,612 = 102,512 \]
Now, looking at the options provided:
- 1,000,000
- 150,000
- 10,000
- 100,000
The total number of cells, approximately, is 102,512, which is closest to 100,000.
So, the correct response is: 100,000.
