21 years old in dog years


Asked by maham237 @ in Mathematics viewed by 289 People


To convert dog years to human year, count 21 human years for the first two dog years and then 4 human years per dog year for each dog year thereafter. Write an expression that represents the human age of a dog that is Y dog years old, where Y is greater than 2.

Answered by maham237 @



(y-2)4 + 21
You subtract two because the 21 accounts for it and then whatever you have left multiplied by 4 and added to 21 is the amount of years after conversion.
