At time t = 0, 5 grams of salt are dissolved into 15 liters of water. Brine with concentration of salt 4 grams per liter is added at a rate of 2 liters per minute. The tank is well mixed and drained at 2 liters per minute. Let ɩ be the Q amount of salt, in grams, in the solution after ₺ minutes t have elapsed. Find a differential equation for the rate of change in the amount of salt, dQ/at, in terms of the amount of salt in the solution Q. dQ dt grams/minute
