I want to know the answer to the following question:
Approximately how many total viewers watched the England World Cup qualifier on the internet on 10 October 2009?
All the background I'm provided with is that "The number of subscribers, paying between £4.99 and £11.99 each, was estimated at between 250,000 and 300,000 and the total number of viewers at around 500,000.". Is that enough to answer the question?
