Gunner has a box of mittens with 20 fewer pairs than a box of plugs. He decides to put 30 more pairs of plugs into the box of plugs. If the box of mittens has 150 pairs of mittens, how many plugs are there? Let's think step by step and output the final answer after "####".

Since there are 20 fewer mittens pairs than the plugs, there are 150+20 = 170 pairs of plugs.
When Gunner decides to add 30 more plugs pairs into the box of plugs, the number of plug pairs increases to 170+30 = <<170+30=200>>200
Since a pair has two, the 200 pairs of plugs total 200*2 = <<200*2=400>>400 plugs.
#### 400
