Water which has a concentration of 5g of salt per gallon flows into the tank at a rate of 7 gallons/min, and the mixture is stirred to a uniform concentration. Water also leaks from the tank at the same rate, 7 gallons/min. Find a differential equation describing the rate of change of salt in the tank. Hint: The concentration of salt in the tank is S(t)/77, where S(t) is the total amount of salt in the tank at time t, in grams. S'(t), the rate of change of salt in the tank over time, is equal to the [rate in] - [rate out].
