a 100-gallon is filled with pure water. salt water of concentration .1 pounds of sat per gallon of water is pumped into the tank at 25 gallons per minuet. brine leaves the tank at the same rate. let y(t) denote the amount of salt in the tank at time t. Set up and solve a first order differential equation for hte unknown function y(t) and compute teh amount of salt in the tank in the long run. Find y(infinity) = lim y(t) as t approaches infinity
