Nalani had two female dogs that were expecting and after a month gave birth to 10 puppies each. She then sold 3/4 of the puppies after they came of age, each at $200. Calculate the total amount of money she received from the sale of the puppies. Let's think first. Chain of thought:

If the two expectant dogs gave birth to 10 puppies each, the total number of puppies Nalani had is 10 + 10 = 20. When they came of age, Nalani sold 3 / 4 of the dogs, a total of 3 / 4 * 20 = 15 dogs. If each dog sold for $200, Nalani received 15 * 200 = $3000 from the sale of the dogs.
Therefore, the answer is 3000.
