Answer 1

The awnser to the problem is 3

Answer 2

3

Explanation:

Start with Krysta and work backwards, taking the wording literally.

Krysta's height: x

So that means that if Kathleen is 6 in shorter, then:

Kathleen's height: x - 6

If Evan is 13 inches taller than Kathleen, then:

Evan's height: x - 6 + 13

If David is 2 inches shorter than Evan, then:

David's height: x - 6 + 13 - 2

If Janice is 4 inches shorter than David, then:

Janice's height: x - 6 + 13 - 2 - 4

Let's simplify all those now:

Krysta: x

Kathleen: x - 6

Evan: x + 7

David: x + 5

Janice: x + 3

If Krysta is x, and Janice is x + 3, that means that Janice is 3 inches taller than Krysta.
