The question is:
A Woman is selling an (X) amount of Oranges
The first time she sold half of the total Oranges and half of an Orange.
The second time she sold half of what is left of the Oranges and also half of an Orange.
The third time she sold half of what's left of the Oranges and half of an Orange. After that all her oranges are sold.
What is the total numbers of Oranges?
I'm not sure how to express that in an algrebraic expression and go about solving it.

Do you have the correct information?
If she sold three halforanges, she will still have at least a halforange left. So how could it be "that all her oranges are sold"?
Please repost. Thanks for asking.
