A 2 lbs of salt was dissolved completely into 100 gallons of pure water. After an hour, a brine solution containing 7 Ibs per gallon flows into the tank at the rate of 3 gallon per minute and a well mix solution is slow out into the tank at the same rate. Determine the amount of salt in the tank after 14 minutes. (unit not needed)
