Trina was playing with her new puppy last night. She began to think about what she had read in a book
about dogs. It said that for every year a dog lives it actually is the same as 7 human years. She looked at
her 4 month-old puppy and wondered how many human years old her puppy was? Using as much math
language and good reasoning as you can, figure out how many human years old Trina's puppy is?
