These two graphs illustrate the average cost and sold percentage of tickets at a theatre in 2010 and 2011, which were recorded quarterly.

For most of the 8-quarter period, the price remained stable at a very high level, reaching $10.5. The exceptions were in the 1st and 2nd quarters of 2010 (around $9.2) and in the 2nd quarter of 2011 (around $10.2).

The percentage of tickets sold follows a different pattern compared to the price. In the first 3 quarters of each year, the tickets did not sell out, with approximately 59% sold in 2010, and 24%, 24%, and 50% respectively in 2011.

Based on these two charts, the amount of money spent on tickets at the theatre did not affect the number of tickets sold.
