For the funfair, the school organizers ordered 30 rolls of tickets. Each roll of tickets has 100 tickets. The 4th graders bought 30% of the tickets while the 5th graders bought 50% of the remaining tickets. Then the 6th graders bought a total of 100 tickets. How many tickets were left unsold? Let's think step by step and output the final answer after "####".

There were a total of 30 x 100 = <<30*100=3000>>3000 tickets ordered by the school organizers.
The 4th graders bought 3000 x 30/100 = <<3000*30/100=900>>900 tickets.
So, there were 3000 - 900 = <<3000-900=2100>>2100 tickets left for the other two grade levels.
The 5th graders bought 2100 x 50/100 = <<2100*50/100=1050>>1050 tickets.
So, 2100 - 1050 = <<2100-1050=1050>>1050 tickets were left then.
Since 100 tickets were bought by the 6th graders, therefore 1050 - 100 = <<950=950>>950 tickets were left unsold.
#### 950
