0 pts 2. (10 Points) Suppose a bucket is being filled with 2 cups per minute of water, concentrated with 2 grams per cup of sugar. The concentrated water is then being drained at a rate of 3 cups per minute. We assume the bucket is initially filled to the brim with 100 cups of clean water (no sugar at first), and is always well-mixed. The amount of sugar (grams) in the bucket, y, after t minutes can be modeled by: 3y = 100- a.) Explain how this model was constructed. That is, use the information given to reconstruct this equation. You should be able to explain the origin of every value (e.g. "the number 130 comes from." ) b.) Using the method of Integrating Factors, solve the ODE. c.) Since the volume of water entering the bucket is smaller than the volume of water exciting the bucket, the bucket will begin to drain. How much sugar will be in the bucket when the bucket is half full
