Yesterday morning, she got 68 gallons of milk and in the evening, she got 82 gallons. This morning, she got 18 gallons fewer than she had yesterday morning. After selling some gallons of milk in the afternoon, Mrs. Lim has only 24 gallons left. How much was her revenue for the milk if each gallon costs $3.50? How many gallons did Mrs. Lim get this morning? ** Mrs. Lim got 68 gallons - 18 gallons = <<68-18=50>>50 gallons this morning. How many gallons did Mrs. Lim get in total? ** So she was able to get a total of 68 gallons + 82 gallons + 50 gallons = <<68+82+50=200>>200 gallons.
