every 5 minutes, 2 tickets are sold....that means in every 5/2 = 2.5 minutes, 1 ticket is sold.

so we are dealing with 80 minutes....if every 2.5 minutes, 1 ticket is sold, then in 80 minutes 80/2.5 = 32 tickets are sold.

And there were 450 tickets sold in advance.

for a total of 450 + 32 = 482 tickets sold <==
