A tank contains 60kg of salt and 2000L of water. A solution of a concentration .015kg of salt per liter enters a tank at the rate 6L/min. The solution is mixed and drains from the tank at the same rate.

Helpful Hints:

A differential Equation has to be used

Net Rate= (Rate In - Rate Out)

Initial Concentration is .03 kg/L

My answer was y=(((e^(6/-2000)t+ln(.08991))-.09)(-2000/6) but it was wrong

I dont know if y(0)=.03 or y(0)=60

Any help will be greatly appreciated.
