Question

Sara's office recycled a total of 12 pounds of paper over 4 weeks. How many weeks will it take Sara's office to recycle a total of 48 pounds of paper? Solve using unit rates

Answer 1

They averaged 3lbs. a week for 4 weeks to get 12lb. They would need an additional 36lbs. to get to 48lbs. Averaging the same 3lbs. per week, this would take an additional 12 weeks for a total of 16 weeks.
