I want to know the answer to the following question:
How much did tourists spend in Boston in 2011?
All the background I'm provided with is that "Tourism also composes a large part of Boston's economy, with 21.2 million domestic and international visitors spending $8.3 billion in 2011; excluding visitors from Canada and Mexico, over 1.4 million international tourists visited Boston in 2014, with those from China and the United Kingdom leading the list.". Is that enough to answer the question?
Answer: yes
