My question is: At the pet store, there are 7 puppies and 6 kittens for sale. Two puppies and three kittens are sold. How many pets remain at the store? Your thoughts:

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.

There are 7 + 6 = 13 pets. They sell 2 + 3 = 5 pets. After the sales, there are 13 - 5 = 8 pets. The final answer: 8.
