Final answer:
The minimum number of investors required to vote for a change in top management depends on the company's bylaws and regulations. Investors 1 and 2, if they agree to vote together, would have a combined total of 38,000 shares.
Step-by-step explanation:
In order to change the company's top management, the shareholders of The Darkroom Windowshade Company would need to vote. The minimum number of shareholders required to pass a vote depends on the company's bylaws and any applicable regulations. Without knowing the specific requirements of the company, it is not possible to determine the minimum number of investors required to vote for this change.
If investors 1 and 2 agree to vote together, they would have a combined total of 38,000 shares (20,000 + 18,000). However, their ability to always get their way in how the company is run would depend on the voting power of the other shareholders.
It is important to note that shareholders' voting power is typically determined by the number of shares they own. The more shares a shareholder owns, the more voting power they have. Therefore, shareholders with a higher number of shares can have a greater influence on the company's decisions.
