Since the number of cells in each petri dish is given, you just need to add them together to find the total number of cells.
22,340 + 43,560 + 36,612 = 102,512
Therefore, there are approximately 102,512 cells in total.

The total number of cells is:
22,340 + 43,560 + 36,612 = 102,512
Therefore, the correct response is:
D 100,000

To find the best estimate for x, we will solve the equation:
x - 50 = 94 + 189
x - 50 = 283
Now, we can find the value of x by adding 50 to both sides:
x = 333
Therefore, the best estimate for x is:
D 333
