Answer :
Final answer:
Alex bought a total of 74.5 pounds of pet food.
Explanation:
To find the total pounds of pet food Alex bought, we need to add the weights of the dog food, cat food, and fish food.
Four 15-pound bags of dog food would be 4 * 15 = 60 pounds.
Three 4 and 1/2 pound bags of cat food would be 3 * 4.5 = 13.5 pounds.
Two 1/2 pound bags of fish food would be 2 * 0.5 = 1 pound.
Adding up these amounts, Alex bought a total of 60 + 13.5 + 1 = 74.5 pounds of pet food.
