a. A tank holds 1000 liters of water, in which 15 kg of salt is dissolved. Pure water enters the tank at the rate of 10 liters per minute. The solution is kept thoroughly mixed and is drained from the tank at the same rate. If m is the mass of salt in the tank at time t, which of the following options describes the rate of change of the mass of salt in the tank? Odm/dt = 15- (m/100) Odm/dt = (15-m)/1000 Odm/dt = -m/100 Odm/dt = - 15/100
