Final answer:
After acquiring Old-world Enterprises, NewWorld Corporation will have earnings per share of $2.40.
Step-by-step explanation:
In the given scenario, Newsworld Corporation acquires Old-world Enterprises using its own stock. Since Old-world has earnings of $4 per share and 750,000 shares outstanding, its total earnings are $4 * 750,000 = $3,000,000. After the acquisition, Newsworld Corporation will have a total of 750,000 + 500,000 = 1,250,000 shares outstanding. Therefore, Newsworld's earnings per share after the acquisition will be $3,000,000 / 1,250,000 = $2.40 per share.
