To find the cost of the shirt after a 20% markdown, you'll need to calculate the markdown amount and subtract it from the original price \( x \).
1. **Calculate the markdown amount**:
\[
\text{Markdown} = 0.20 \times x
\]
2. **Subtract the markdown from the original price**:
\[
\text{Cost after markdown} = x - (0.20 \times x)
\]
3. **Simplify the expression**:
\[
\text{Cost after markdown} = x - 0.20x = 0.80x
\]
Therefore, the cost of the shirt after the 20% markdown is \( 0.80x \).
So, the answer is:
**A. \( 0.80x \)**.
1. **Calculate the markdown amount**:
\[

\]
Therefore, the cost of the shirt after the 20% markdown is \( 0.80x \).
So, the answer is:
**A. \( 0.80x \)**.
