6 pies.
If 8 teachers finish one whole pie, and they need to feed 47, then they need 6 pies with 8 slices each aka 48 slices total, there will be one slice leftover for the principal :D
The answer will be: 1,000,000 if you round to the nearest hundred thousands. Hope it helps! :D
I believe the answer is B because you have to do the Vertical Line Test.<span />
