conversations.value: I need a clearer understanding of how to solve: Hannah has three dogs. The first dog eats 1.5 cups of dog food a day. The second dog eats twice as much while the third dog eats 2.5 cups more than the second dog. How many cups of dog food should Hannah prepare in a day for her three dogs?
conversations.from: assistant
conversations.value: The second dog eats 1.5 x 2 = 3 cups of dog food.
  The third dog eats 3 + 2.5 = 5.5 cups.
  So, Hannah should prepare 1.5 + 3 + 5.5 = 10 cups.
