Set up the differentiаl equаtiоn:  There is а tank with 80 gallоns оf water and initially has 20kg of salt. Water, with 2kg of salt per gallon, is pumped into the tank at 10 gal/min. The mixture is kept uniform by stirring, and the (salty) water leaves the tank also at 10 gal/min, thereby keeping the volume of water at 80 gallons. Write a differential equation in the form dx/dt=f(x,t) where x(t) is the amount of kg salt in the tank at time t.
