Final answer:
The minimum number of investors needed to vote to change the company's top management is determined by a majority vote. In this case, only 2 investors are needed if investors 1 and 2 vote together.
Step-by-step explanation:
The minimum number of investors it would take to vote to change the company's top management is determined by a majority vote. In this case, the majority vote requires more than half of the outstanding shares. The total number of outstanding shares in the Darkroom Windowshade Company is 100,000.
Investors 1 and 2 together own 20,000 + 18,000 = 38,000 shares. To calculate the minimum number of investors needed for a majority vote, we need to find the half of the total outstanding shares, which is 100,000 / 2 = 50,000 shares.
Since investors 1 and 2 own more shares than the required majority vote threshold, only 2 investors are needed to vote to change the company's top management. They can be certain of always getting their way as long as they vote together.
