Answer:
23
Explanation:
Mary started with 23 cookies since she ended with 5, gave half to her brother before that so that equals 10 and then before that she ate 1 cookie so that means she would have 11 and then she gave half before that to her sister so that equals 22 and she ate a cookie before that so that equals 23 cookies in total.
