Answer:
3
Explanation:
We know Ms.Smith is buying avocados and needs 12, we also are provided with the fact that she buys them in bags of 5.
If you take a look at the picture, we need to find a bag that fits 12 avocados in, this would be 3. As in 3 bags that contain 15 avocados in total, though excessive amount, this is the bag that she would need to benefit her the most.
