Question

Paula has a dog that weighs 3 times as much as Carla's dog. The total weight of the dogs is 76 pounds. How much does Paula's dog weigh? Use the diagram to find the weight of Paula's dog.

Answer 1

Paula's dog weighs 57lbs and Carla's dog weighs 19lbs

Explanation:

So Paula's dog will be "p" and Carla's dog will be "c"

This means p = 3c and that p + c = 76

Replace p with 3c

3c + c = 76

4c = 76

c = 19

Now solve for p

p + (19) = 76

p = 57
