To find the selling price of the stock after a 20% profit, you can use the following steps:
1. Identify the original price of the stock, which is \( x \) dollars.
2. A profit of 20% on \( x \) is calculated as \( 0.20x \).
3. Therefore, the selling price would be the original price plus the profit:
\[
\text{Selling Price} = x + 0.20x = 1.20x
\]
So, the correct mathematical expression for the selling price is:
**1.2x**
