Paula has a dog that weights 3 times as much as Carla's dog. The total weight of the dogs is 48 pound. How much does Paula's dog weight?
Paula's dog is 36 lbs
Use the equation 48=3x+x
Add like terms: 48=4x
Divide: 12=x (x=Carla's dog's weight)
Then Multiply x by 3 to get Paula's dog's weight and you get 36 lbs
