Cats are older than you think

Algebra Level 1

Experts typically agree that the first two years of a cat's life are equal to the first $25$ years of a human’s. After that, each additional year is equal to approximately $4$ years.

Grey has currently survived for $10$ years and celebrated this milestone by getting many boxes. What is his equivalent human age?

57 human years 14 human years 70 human years 10 human years 40 human years 82 human years 53 human years

(10-2)*4+25=57 years.

So that means I'm a twelve year old cat.

yeah, then I'm only 1 year 5 month, LOL

I'm only 13 years old (in human age). I can't be sure what my cat age is because it's undefined in the problem. I can't assume that any human age below 25 is calculated proportionally.

Given that Grey's age= $10$ years

We know that First two years of a cat's life is equivalent to $25$ years of a human's life. Therefore number of additional years after 2 years that Grey has survived = $10-2= 8\ \text {years}$ 1 year lived by a cat is equivalent to 4 human years

Therefore $8 \ \text {years}= 8 * 4 = 32 \ \text {years}$ Therefore Grey's age is equivalent to $25+32 = 57$ human years.

Great job :)

Does that mean I am a year-and-three-month old cat??
