conversations.value: Find the answer to the math problem: Mark just got a new puppy that cost $10. He also bought enough food for 3 weeks. He knows the puppy eats 1/3 cup of food a day. A bag of food with 3.5 cups costs $2. How much did all of this cost him?

conversations.value: He needs food for 21 days because 3 x 7 = 21
  The puppy will eat 7 cups of food because 21 x (1/3) = 7
  He needs 2 bags of food because 7 / 3.5 = 2
  The food will cost him $4 because 2 x 2 = 4
  It will cost $14 in total because 10 + 4 = 14
