Atank contains 30 lb of salt dissolved in 500 gallons of water. a brine solution is pumped into the tank at a rate of 5 gal/min; it mixes with the solution there, and then the mixture is pumped out at a rate of 5 gal/min. determine a(t), the amount of salt in the tank at time t, if the concentration of salt in the inflow is variable and given by cin(t) = 2 + sin(t/4) lb/gal. a(t) = incorrect: your answer is incorrect. lb without actually graphing, conjecture what the solution curve of the ivp should look like. then use a graphing utility to plot the graph of the solution on the interval [0, 300].
