Homework Statement
Salt water pours into a 10 liter tank at a rate of 4 l/min. Its concentration is 2 g/l. The brine in the tank is well mixed and it drains out at a rate of 4 l/min. Call y the grams of salt in the tank at time t. The tank is initially full of fresh water. Solve the differential equation that models the salt in the tank.
Homework Equations
dy/dx = rate in - rate out
y(t)= grams of salt (y) at time (t)
The Attempt at a Solution
I worked the problem and got the differential equation y'=8-(y/10)4 now I don't know how to solve that to get a particular solution assuming the initial condition y(0)=0
