Answer:
The answer is: 390 stocks
Step-by-step explanation:
The §318 stock attribution rules stipulates that a person owns what their spouse, children, grandchildren, or parents own. This means that DeWitt Corporation (since Jennifer owns 50%) owns its 130 stocks plus Jennifer's 130 stocks and Dan's 130 stocks. So DeWitt basically owns all of Lansing Corporation according to the §318 stock attribution rules. That doesn't mean that Jane owns half of Lansing though.
