From the graph above that was given, we can see a lot of things.
Starting with year 2010, in q1 price for the tickets were about 9 and 9 and half pounds, which can be considered as an expensive type of the tickets in comparison with other ones. Then, we have q2 which has the same data as a q1 consist of. But the next q3 is more expensive than previous two. Its price became 10.5 pounds, raised by one pound. And the price is standing until 2011’s q2. It means that in that time people had to pay more. but for their surprise, in 2011 q3 there was some kind of discount. people had to pay for half pound less. but, nevermind, in the q4 we see that this discount had disappeared. what we were talking about was about the prices, but what about selling the tickets?
for my own surprise, tickets were sold more when their prices where higher. the pure examples are q4’s in 2010 and 2011. although, nothing is easy in the words. in q1 and q2 of 2011, tickets were harder to sell. the similar thing was with q3 of 2010, and a little bit more they were selling in 2010’s q1 and q2.
