I need a clearer understanding of how to solve: Lily got a new puppy for her birthday.  She was responsible for feeding the puppy 1/4 cup of food three times a day for two weeks starting tomorrow.  For the following 2 weeks, Lily will feed him 1/2 cup of food twice a day.  She has fed him 1/2 cup of food today.  Including today, how much food will the puppy eat over the next 4 weeks?
