10. Cally Culus is mixing stuff again. She has a large bucket containing 200 liters of water in which 30 grams of salt is dissolved. A brine solution containing 2 gram of salt per liter is being pumped into the tank at a rate of 5 liters per minute. The well mixed solutions is then pumped out at the same rate of 5 liters per minute. Let A represent the number of grams of salt in the tank and let t represent the time in minutes. Set up a differential equation to model this situation. (a)

10. Cally Culus is mixing stuff again. She has a large bucket containing 200 liters of water in which 30 grams of salt is dissolved. A brine solution containing 2 grams of salt per liter is being pumped into the tank at a rate of 5 liters per minute. The well-mixed solution is then pumped out at the same rate of 5 liters per minute. Let A represent the number of grams of salt in the tank and let t represent the time in minutes. (a) Set up a differential equation to model this situation. (b) Use the methods of Chapter 2 to solve the DE and find the function A(t). Show all work!
