Final answer:
The current stock price is $20 per share.
Step-by-step explanation:
The PE ratio for a firm is the price-to-earnings ratio, which is calculated by dividing the stock price by the earnings per share. In this case, the PE ratio is 10 and the earnings per share is $2.
To find the current stock price, we can use the formula:
Stock Price = PE Ratio * Earnings per Share
Substituting the values in, we get:
Stock Price = 10 * $2 = $20
Therefore, the current stock price for a firm with earnings of $2 per share and a PE ratio of 10 is $20 per share.
