The items he returned were valued at $700 + $500 = $<<700+500=1200>>1200
So far he is out 3000-1200 = <<3000-1200=1800>>1800 after recouping 1200.
An item that is 20% more expensive cost 1 + .2 = 1.2 times as much as the item
So that means the bike he sold cost $500 * 1.2 = $<<500*1.2=600>>600
He sold it for $600 * .8 = $<<600*.8=480>>480
From the bike that he had bought for 600, he was out 600-480 =<<600-480=120>>120
So far he is out 1800+120 = <<1800+120=1920>>1920
If he also bought a toaster worth 100, he was out 1920+100 = <<1920+100=2020>>2020
