Cody was going to sell all of his stamp collection to buy a video game. after selling half of them he changed his mind. he then bought seventeen more. how many did he start with if he now has 44?
He now has 44 so subtract 17 from that and you get 27 (1/2 of the number of his original stamp collection). Then add 27 +27 and you get 54. I believe 54 is the answer. Hope that helps!
