maybe you start from the origin
i'm not sure on c, sorry.
56 packs of crazy straws
1. 224 x 2= 448 *the total straws*
2. once you have that, divide the 448 by 8 so you can find out the packages he started with. you get 56.
3. check your work by doing 56 x 8, which is 448, just to make sure.
4. divide 448 by two which gives you 224, which is what you started with.
