The shareholder equity is equal to:
$28/share * 13 700 shares = $ 383,600
This is the total capital of Davidson International. Now, assuming that there is no additional income since it is not implied in the problem, the total equity does not change. However, the shares become: 13,700 + 500 = 14 200 shares.
Price per share now becomes:
$383 600 / 14 200 shares = $27/share
