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?
Thoughts? Step-by-step reasoning:
User
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.
Thus, the answer is 10.
