Answer: 5%
Step-by-step explanation: First, divide 200,000 by 10,000 which gives you 20. I pretended like everyone in the group contributed $10,000, meaning that their were 20 people that all contributed $10,000. To find out how much of company she owned, divide 100 by 20 cause 100% is all of the company owned. And my answer was 5%.
