Final answer:
Great Corporation's investment in SOS Corporation after the sale of additional shares is $405,000.
Step-by-step explanation:
To calculate the investment in SOS Corporation by Great Corporation after the sale of additional shares, we need to consider the acquisition of the initial 90% interest and the subsequent sale of new shares.
The initial investment was made at book value, which was $810,000. This means that Great Corporation acquired 90% of SOS Corporation for $810,000.
After the sale of 10,000 new shares of common stock to the general public, we need to adjust the investment. Since Great Corporation owns 90% of SOS Corporation, it will still own 90% of the additional shares. So, the investment after the sale would be 90% of the total value of the new shares sold.
To calculate the total value of the new shares sold, we multiply the number of shares (10,000) by the sale price per share ($45). So, the total value of the new shares sold is $450,000.
Therefore, the investment in SOS Corporation by Great Corporation after the sale would be 90% of $450,000, which is $405,000.
