"Rocky is 44 years old," said Jenna to her friend.

"She is? But your brother said your dog was younger than that. And I just asked him a

few minutes ago. Weird."

"Hey!" said Alex snooping by the door.  "That's because Jenna doesn't use the simple

formula to multiply a dog's age by 7."

"I may not use simple, but I use what's more accurate. A dog's first year of life is about 15

human years. A dog's second year equals about 9 human years. Every year after that is

about 5 human years. That's why Rocky is 44 years old."

What's Rocky's real age?

 

How old would Alex say Rocky is?

Because only the first year and second year of a dog's life are calculated differently, you can add 15 and 9, subtract that from 44, and then divide the result by 5 to find Rocky's real age.

15+9=24

44-24=20

20/5=4

4+2 (15 and 9)=6

So Rocky's actual age is 6.

Alex just multiplies a dog's age by 7, so Alex would say that Rocky is 6 * 7 =42 years old.

Hope you found this useful!
