Question: Jane picked 64 apples at the orchard. She sorted them into 4 different baskets to send to her friends. When Jane wasn't looking her sister took 3 apples from each of the baskets. How many apples are in each basket now?
Stream-of-consciousness: Before her sister took some there were 64 / 4 = 16 apples in each basket. After her sister took some each pile had 16 - 3 = 13 apples in each basket.
