15. a tank initially contains 50 galions of water with a concentration of 2 lb/gal salt. water that is 3 lb/gal salt enters the tank at a rate of 5 gal/min, and the well-stirred mixture is allowed to leave the tank at a rate of 2 gal/min. if q(t) denotes the amount of salt in the tank at time t, determine an initial value problem that can be used to model this scenario. then, find the solution.
