Q7)The town of Sterling recycled 385,395 aluminum cans in January of 2010. It recycled 562,543 cans in March of 2010. How many more cans were recycled in March than in January?
Answers
Answer:
Recycling centers store the used cans they buy from can collectors in trailers. A full trailer holds 15,000 pounds of loose cans. There are about 24 aluminum cans in a pound. When the trailer is full, it is hauled to a processing plant where the loose cans are pressed into huge 800-pound bales. Bales are loaded into rail boxcars for a trip to an aluminum company remelting plant. Remelted cans are rolled into new aluminum for new cans.
If you are in a state with a bottle bill, the value of each container is five or ten cents. If your state does not have a bottle bill, find out how much per pound your nearest recycling center pays for aluminum. If you have no recycling center near you, ask a local scrap metal dealer for the price paid for aluminum scrap. Use a price of 60 cents per pound if you cannot get a local figure.
