I want to know the answer to the following question:
How much was casino revenue in 2006?
All the background I'm provided with is that "With casino revenue declining from $5.2 billion in 2006 to $2.9 billion in 2013, the state saw a drop in money from its 8% tax on those earnings, which is used to fund programs for senior citizens and the disabled.". Is that enough to answer the question?
Answer: yes
