Final answer:
Each dog will get 16 dog treats.
Step-by-step explanation:
To find out how many dog treats each dog will get, we can divide the total number of dog treats by the number of dogs.
In this case, Ms. Sanchez has 16 dog treats in each package and she buys 4 packages, so she has a total of 16 x 4 = 64 dog treats.
Since Ms. Sanchez has 4 dogs, we can divide the total number of dog treats by the number of dogs: 64 ÷ 4 = 16.
Therefore, each dog will get 16 dog treats.
