Answer:
105
Step-by-step explanation:
Complete Question:
<em>"Ejay bought a pack of peanut bars from the neighborhood store. He ate 1/3 of the context immediately. He gave 20 pieces to his sister Aileen. Then he ate 1/2 of the remaining bars. If he has 25 peanut bars left after, how many bars did the pack originally contain?"</em>

Let original amount be x
He ate 1/3 immediately so remaining
x - 1/3x
He gave 20 to Aileen, remaining:
(x - 1/3x) - 20
He ate half of remaining, remaining now:
(x - 1/3x) - 20 - 1/2((x - 1/3x) - 20)
Now, he has 25 left. So the previous equation is equal to 25. Then we solve for x:
The pack originally had 105 bars
