A tank contains 1520 L of pure water. A solution that contains 0.06 kg of sugar per liter enters a tank at the rate 9 Umin The solution is mixed and drains
from the tank at the same rate.
(a) How much sugar is in the tank initially?
0 (kg)
(b) Find the amount of sugar in the tank after t minutes.
amount =| |(kg)

(your answer should be a function of t)
(c) Find the concentration of sugar in the solution in the tank after 39 minutes.
concentration=
