This is an ODE related question,
A 1500 L tank initally contains 600 L of water with 50 kg ofsalt in it. Water enters the tank at a rate of 9 L/hour and thewater entering the tank has a salt concentration 0.1 kg/L. A wellmixed solution leaves the tank at a rate of 6L/hour.
a. The integrating factor that can be used to solved thedifferential equation for q(t) is?
b. The amount of salt in the tank when the tank overflowsis?
