Question: 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? Think carefully first, then make a decision:
1 week has 7 days so 2 weeks will have 2 * 7 = 14 days. The puppy will eat 1 / 4c three times a day so .25 * 3 = .75 cups per day. The puppy will eat .75 cups of food a day for 14 days for a total of .75 * 14 = 10.5 cups. The puppy will then eat '.5 cup of food twice a day so .5 * 2 = 1 cup per day. The puppy will eat 1 cup of food a day for 14 days for a total of 1 * 14 = 14 cups per day. She has already fed him .5 cup of food and he will eat 10.5 cups and another 14 cups for a total of .5 + 10.5 + 14 = 25 cups of food. So the answer is 25.
