Answer 1

A recycling company recycles wet and dry wastes. In a week, each ton of dry waste takes 35 hours for collection and 55 hours for processing. Each ton of wet waste takes 42 hours for collection and 63 hours for processing. The company's collection workforce can work for maximum 150 hours in a week, and the processing machine can work for maximum 200 hours in a week. Let D represent the number of tons of dry waste that the company can recycle in a week and W represent the number of tons of wet waste that the company can recycle in a week. Which of the following statements best explains whether the company will be able to recycle 3 tons of dry waste and 2 tons of wet waste in a week?
