There were 3 eggs.
umm... can you please explain
half of three eggs is 1.5, plus half an egg is 2 eggs, leaving one.
The next day, he takes half the egg, plus a half. That is all the eggs.
the third day, no eggs remain to get.
You could work backwards to get the answer.
On the third day, he bought half the egg(s) plus half an egg. There was nothing left.
That means that what was left plus half an egg was half of what was there after he bought half of the eggs.
Therefore before he walked in, there were:
2 × (0+1/2)
=1 egg
Same happened on the second day, so before he walked in, there were:
2 × (1+1/2)
= 3 eggs.
Same happened on the first day, so before he walked in, there were:
2 × (3+1/2)
= 7 eggs.
Remember, we have assumed that there were no more nor less eggs than what he bought, no one else bought the eggs, and he bought what was left there from three days ago (yuck!).
You can now start with 7 eggs and go through the scenario and see if it still works.
