Answer: 250 pounds + 125 pounds = 375 pounds of dog food.
Step-by-step explanation:
For the 10-pound bags:
25 bags * 10 pounds/bag = 25 x 10 = 250 pounds
For the 25-pound bags:
5 bags * 25 pounds/bag = 5 x 25 = 125 pounds
Therefore, the pet store sells a total of:
250 pounds + 125 pounds = 375 pounds of dog food.
