For interrupting, Jerry got 5 points per interruption * 2 interruptions = <<5*2=10>>10 points
For insulting, he got 10 points per insult * 4 insults = <<10*4=40>>40 points
To get to the 100 limit points, Jerry has 100 points - 10 points - 40 points = <<100-10-40=50>>50 points left
He still has 50 points / 25 points per throw = <<50/25=2>>2 throws
