Problem Analysis

We are given the ages of a wolf, a hare, and a fox. The wolf lives for 20 years, the hare lives for 12 years, and the fox lives 3 years less than the combined age of the wolf and the hare. We need to determine the age of the fox.

Solution

Let's denote the age of the fox as F.

Given: - Age of the wolf (W) = 20 years - Age of the hare (H) = 12 years - Age of the fox (F) = (W + H) - 3 years

To find the age of the fox, we substitute the given values into the equation for the age of the fox:

F = (W + H) - 3

Substituting the given values:

F = (20 + 12) - 3

Simplifying the equation:

F = 32 - 3

F = 29

Therefore, the fox lives for 29 years.

Answer

The fox lives for 29 years.
