1. The problem asks to fill in the cumulative percentage $c\%$ for each range of shares held. 2. The cumulative percentage is the running total of the percentages up to and including each category. 3. Start with the first category: $0$ and under $50$ shares, which has $25\%$. So, $c\% = 25$. 4. For the second category: $50$ and under $100$ shares, add $19\%$ to the previous cumulative percentage $25\%$: $$c\% = 25 + 19 = 44$$ 5. For the third category: $100$ and under $500$ shares, add $41\%$ to the previous cumulative percentage $44\%$: $$c\% = 44 + 41 = 85$$ 6. For the fourth category: $500$ and under $1000$ shares, add $12\%$ to the previous cumulative percentage $85\%$: $$c\% = 85 + 12 = 97$$ 7. For the fifth category: $1000$ and under $2000$ shares, add $3\%$ to the previous cumulative percentage $97\%$: $$c\% = 97 + 3 = 100$$ 8. The cumulative percentages are integers and sum to $100\%$ as expected. Final cumulative percentages $c\%$ are: - $0$ and under $50$: $25$\% - $50$ and under $100$: $44$\% - $100$ and under $500$: $85$\% - $500$ and under $1000$: $97$\% - $1000$ and under $2000$: $100$\%
