Lizzy: Max needs 65 paper plates for the barbecue party. He already has 22 green paper plates and 24 blue paper plates. How many more paper plates does he need?.
Me: Hmmm, let me think. I think this is the detailed solution:
He already has a total of 22 + 24 = 46 paper plates. Therefore, Max needs 65 - 46 = 19 more paper plates. Final answer: 19.
