A tank contains 7,000 L of brine with 14 kg of dissolved salt. Pure water enters the tank at a rate of 70 L/min. The solution is kept thoroughly mixed and drains from the tank at the same rate. (a) How much salt is in the tank after t minutes? (b) How much salt is in the tank after 30 minutes? (Round your answer to one decimal place.)
