The old method of finding a dog’s age in human years is to multiply its age by 7.

However, some veterinarians agree that the first two years of a dog’s life together are

equal to 35 human years. Each year after that is equal to 3 human years. Spot is a

9-year-old dog. How old is he in human years?

Use both the old method and the veterinarians’ method to solve the

problem. Show your work below and number the steps you followed in

each method.

Computations will vary. Sample:

Old Method

Veterinarians’ Method

Step 1

Step 3

Step 2

63 years

7 years

21 years

56 years

How do the answers you found with the two methods compare?

years. Using the veterinarians’ method, Spot is 56 years

old in human years.
