Liz works at a pet store. she put 238 bags of cat food on the shelf . customers bought 142 bags. how many bags were left

Well, she put 238 bags on the shelf and customers bought 142. So they probably bought out of the 238 bags on the shelf. So all you have to do is

238-142. And that is 96. So you see, all you have to do is subtract. Hope I helped
