I want to know the answer to the following question:
What was Comcast's profit margin in 2009?
All the background I'm provided with is that "Net profit margin rose from 4.2% in 1999 to 8.4% in 2009, with operating margins improving 31 percent and return on equity doubling to 6.7 percent in the same time span.". Is that enough to answer the question?
Answer: yes
