Final answer:
To find the weight of Marty's dog, set up and solve an equation by adding 24.4 pounds to Marty's cat's weight of 10.4 pounds.
Step-by-step explanation:
To find the weight of Marty's dog, we can set up an equation using the information given. Let w be the weight of his dog. According to the question, 10.4 pounds is 24.4 pounds less than the weight of his dog. So we can write the equation as: w - 24.4 = 10.4. To solve for w, we can add 24.4 to both sides of the equation. This gives us w = 10.4 + 24.4 = 34.8. Therefore, Marty's dog weighs 34.8 pounds.
