My question is: Sonny received 45 boxes of cookies from his friend yesterday. He gave 12 to his brother, 9 to his sister, and he gave 7 to his cousin. How many boxes of cookies were left for him? Your thoughts:

Sonny gave 12 + 9 + 7 = 28 boxes of cookies. Therefore, he was left with 45 - 28 = 17 boxes of cookies. The final answer: 17.
