The voice on the phone was yet another creditor. His coarse voice and rudeness began to infuriate me. "Just how much do I owe?" I demanded. He replied, "You owe $565.60 on your credit card. We will have to add a past due charge of $36, an over limit fee of $32, and a service charge of 6% of the amount owed on the credit card." I told him I would send a check for the full amount immediately. For how much should the check be written?

Nathan 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, Nathan finds objects other than aluminum cans in the recycling boxes. He estimates that ten percent of the weight of the material in the boxes is nonrecyclable junk. The total weight of all the items collected in the recycling boxes this week was one hundred thirtyeight pounds. What was the weight of the aluminum cans, rounded to the nearest tenth pound?
