A 100-gal tank initially contains 25% dye solution. A 40% dye solution is allowed to enter at a rate of 10 gal/min and the resulting uniform mixture is removed from the tank at the same rate. a. Derive an expression for the amount of dye in the tank as a function of time. b. Find the time t at which the tank contains 23 % dye solution
