| 1. | Isaac collects aluminum cans and takes them to the recycling center every week. He put recycling boxes in all the classrooms, the cafeteria, and the teachers' lounge. He put a sign on each box asking people not to put anything but aluminum cans in them. Every week, though, Isaac finds objects other than aluminum cans in the recycling boxes. He estimates that fifteen percent of the weight of the material in the boxes is non-recyclable junk. The total weight of all the items collected in the recycling boxes this week was one hundred forty-two pounds. What was the weight of the aluminum cans, rounded to the nearest tenth pound?
