Final answer:
After Bob ate 3 apples and then lost 2, he has 0 apples left.
Step-by-step explanation:
If Bob ate 3 apples and he lost 2, we need to calculate the number of apples he has currently. First, we recognize Bob has eaten 3 apples, so those are no longer with him. Then we address the 2 apples that Bob lost. Since these apples are lost, they are also not with him. Therefore, initially, Bob had 3 apples, and losing 2 means he no longer has those two. This means he has no apples left because 3 (eaten) + 2 (lost) equals all 5 apples that are gone. So the answer to the question is: A) 0.
