conversations.value: Solve the math problem: Rollo has 3 guinea pigs, the first guinea pig eats 2 cups of food, the second guinea pig eats twice as much as the first one, and the third guinea pig eats 3 cups more than the second one. How many cups of food does Rollo need to feed all his Guinea pigs?

conversations.value: The second guinea pig eats 2 x 2 = 4 cups of food.
  The third guinea pig eats 4 + 3 = 7 cups of food.
  Therefore, Rollo needs a total of 2 + 4 + 7 = 13 cups of food for the guinea pig.
