Estabilish and solve suitable IVP(s) using solution to IVP to find answer to every question. A 1,000 liter tank has 400 liter of salt water with 20 grams of the salt dissolved in it. Salt water with the concentration of c(t)= (t/10)e^(1-t/30) grams/L flows in at the rate of 2 L/min. Find how much salt is in water after one hour of operation.
