there are three petri dishes in a labratory. The first one contains 22,340 cells, the second contains 43,560 cells, and the last dish contains 36,612 cells. Approximatly how many cells are there in total?

A) 10,000
B) 100,000
C) 1,000,000
D) 150,000

To find the total number of cells, we need to add up the number of cells in each dish.

22,340 + 43,560 + 36,612 = 102,512

The total number of cells is approximately 102,512.

None of the given options exactly matches this number. However, option B) 100,000 is the closest approximation.
