Chapter 12, Problem 12.6CQ

A girl has a large, docile dog she wishes to weigh on a small bathroom scale. She reasons that she can determine her dog’s weight with the following method. First she puts the dog’s two front feet on the scale and records the scale reading. Then she places only the dog's two back feet on the scale and records the reading. She thinks that the sum of the readings will he the dogs weight. Is she correct? Explain your answer.
