Directions: the traditional method for calculating a dogs age in dog years is to multiply its age
in human years by 7. the chart below describes a diffrent method some veterinarians use to estimate
a dog's age based on its size.
size small medium large giant
weight 20 pounds ors less 21-50 pounds 51-90 pounds more than 90 pounds
Age at 2 in 23 dog years 24 dog years 22 dog years 20 dog years
human years
Age increase 4 dog years 5 dog years 6 dog years 7 dog years
eah year after
2 in human years
#1 choose a dog breed in category. you can use the dog breed charts on the following page or do research
to choose a diffrent breed
#2 complete a table to show the dog year equivalent for each breed from 2-5 human years
#3 Let x equal the age, in human years, for a dog that is 2 years old or older. For each of your chosen
breeds, write an expression to model its age in dog years. { Hint: Uses (x -2) in each expression}
#4 choose what you consider to be a really old, but realistic age for people.
#5 for each expression you write, plug in the value you choose in step 4-an old age for a human-for x.
Set each expression equal to (A).
#6 solve each equation, and explain what the solution means. Add the old-age values to your table.
#7 use your solutions to develop a convinicing argument for awhy the method described in the chart is
better than the traditional method.
#8 you may wish to do research to find the average lifespan for each dog breed and use those facts in your
argument
Example dogs:
small dogs medium dogs large dogs giant dogs
border terrier american pit bull boxer Irish wolfhound
chihuahua border collie collie Great dane
pug corgi bulldog Bloodhound
miniture poodel wheaten terrier golden retriever Rottweiler

sir its a (PORTFOLIO) not a (QUIZ)/(TEST) and you said you will help me if i helped you that was the deal I:I
IMMA GIRL MY NAME HAYLEIGH BRO
AND IDK CUZ I GUESS IT NOT THE SAME AS MINE
how is this at all hard?
IDK ITS HARD IM IN 6TH
it's simple-
no hard feelings but ARE YALL THIS DUM?
ANSWER IS SOOOOOO CLEAR
OUCH THAT HURT MY FEELINGS UR MEAN
EVERYTHING HURTS SOME.......i mean.... EVERYTHING HURTS.... EVERYTIME!!!!!!!!!!!!!!!!!!!
To complete the task, follow these steps:
#1: Choose a dog breed in each category. You can either use the provided example dogs or do research to select a different breed.
#2: Complete a table to show the dog year equivalent for each breed from 2-5 human years. This table should have columns for the breed, human age, and dog year equivalent for each year from 2-5.
#3: Let x equal the age, in human years, for a dog that is 2 years old or older. For each chosen breed, write an expression to model its age in dog years. Use the expression (x - 2) in each case, since we are starting from the age of 2.
#4: Choose what you consider to be a really old, but realistic age for people. This will be used as a reference point for comparison.
#5: For each expression you wrote in step 3, plug in the value from step 4 (the old age for a human) for x. Set each expression equal to (A), where A is the dog year equivalent of the old age.
#6: Solve each equation and explain what the solution means. This will give you the dog year equivalent for the chosen breed at the old age. Add these values to your table.
#7: Use the solutions from step 6 to develop a convincing argument for why the method described in the chart is better than the traditional method of multiplying by 7. You may want to do research on the average lifespan for each dog breed to support your argument.
#8: If possible, find the average lifespan for each dog breed from your research and incorporate those facts into your argument. This will further strengthen your case.
By following these steps, you will be able to complete the given task and develop a convincing argument comparing the traditional method of calculating a dog's age in dog years with the method described in the chart.
