We don't know if the Kardashians make this easy or hard to figure out but don't despair if you find out that the answer was so easy, because we all have our bad days and good days. We all miss small details while in the rush of our lives, so it's all ok. Here is the solution process...

We have 3 **Kims **that add up to 30. So 30 divided by 3 is 10. So each **Kim** **Kardashian** is 10.

We have one **Kim, **who is 10, and 2 **Kendall **heads**, **which add up to 18. And 10 + 8 = 18. Both **Kendall**s are 8, so Each **Kendall** is 4.

We have a **Kendall** minus **Kylie**. **Kendall** is 4, and (4 - **Kylie** =2), so **Kylie** is also 2.

**Kim** is 10, **Kendall** is 4 and **Kylie** is 2, but X comes first, so 4X2 =8 and then 8 + **Kim**... 8+10 = 18

So the correct answer is **18**.
