Let's break down the problem and solve it step-by-step.

### Problem Statement
Kala bought 2 CDs at the same price. Including sales tax, she paid a total of $22.40. Each CD had a tax of $1.10. We need to find the price of each CD before tax.

### Solution Steps

1. **Set up the variables:**
   Let $ x $ be the price of each CD before tax.

2. **Calculate total tax on both CDs:**
   Since each CD has a tax of $1.10, the total tax for 2 CDs is:
   \[
   2 \times 1.10 = 2.20
   \]

3. **Set up the equation:**
   The total amount paid by Kala, including tax, is $22.40. This amount includes the price of both CDs and the total tax.
   \[
   2x + 2.20 = 22.40
   \]

4. **Solve for $ x $:**
   - Subtract $2.20 from both sides:
     \[
     2x = 22.40 - 2.20
     \]
     \[
     2x = 20.20
     \]
   - Divide both sides by 2:
     \[
     x = \frac{20.20}{2}
     \]
     \[
     x = 10.10
     \]

### Answer
The price of each CD before tax is **$10.10**.

Here are some related questions for practice:

1. If each CD had a different price, how would you determine the total price?
2. How would the solution change if Kala bought 3 CDs instead?
3. What if the tax per CD was a percentage rather than a fixed amount?
4. How would you set up the problem if the tax was already included in the price of each CD?
5. If Kala had a budget limit, how would you calculate the maximum number of CDs she could buy?

**Tip:** Always verify if the tax is applied per item or to the entire total to avoid calculation errors.

Kala bought 2 CDs that were each the same price. Including sales tax, she paid a total of $22.40. Each CD had a tax of $1.10. What was the price of each CD before tax?
