Homework Statement
A 500 gallon tank is filled with pure water. A solution containing 4lbs of salt per gallon is added at a rate of 2 gallons per minute. The well-mixed solution is drained at a rate of 3 gallons per minute.
A) How long does it take for the container to achieve a concentration of 2lbs/gal?
B) What is the domain of x(t)?
Homework Equations
ODE
The Attempt at a Solution
I found x(t) to be (500-t)^2*(4000-t^2)
then I tried using x(t)/v(t)=2 lbs/gal and this is where I am stuck
