Say you get some % discount for some tickets because you have been going to these concerts for a very long time. The place holding concert has a capacity of 2800. Full fare tickets gives you 3 intervals; 1st interval is between (0 to 400) and the cumulative distribution F(x) = x^2/16000, 2nd interval is from (400 to 1600) and cumulative distribution F(x)= 1/2, the third interval is from (1600 to 2800) and cumulative distribution F(x)= (x-300)/400. How do you find how many tickets you need to reserve for the the full fare?
