Question
![A tank initially contains \( s_0 \) lb of salt dissolved in 400 gallons of water, where \( s_0 \) is some positive number. Starting at time \( t = 0 \), water containing 2 lb of salt per gallon enters the tank at a rate of 8 gallons per minute, and the well-stirred solution leaves the tank at the same rate. Letting \( c(t) \) be the concentration of salt in the tank at time \( t \), show that the limiting concentration—i.e., \(\lim_{{t \to \infty}} c(t)\)—is 2 lb/gal.
---
Write an equation for the rate of salt (in lb/min) that flows into the tank, where \( t \) is the time in minutes.
\[
\text{Flow}_{\text{in}} = 16
\]
Write an equation for the rate of salt (in lb/min) that flows out of the tank, where \( t \) is the time in minutes.
\[
\text{Flow}_{\text{out}} = \Box
