Final answer:
The market price per share of the Carlton Corporation is $50.
Step-by-step explanation:
To find the market price per share of the Carlton Corporation, we need to divide the earnings after taxes by the number of shares outstanding. The earnings after taxes are $5 million and the number of shares outstanding is 2 million. So, the earnings per share is $2.50 ($5 million / 2 million). The P/E ratio is given as 20, which represents the price per earnings. Therefore, the market price per share of the Carlton Corporation is $50 ($2.50 x 20).
