He knows 50 people are showing up and he’s hoping 40 more people will drop in for a total of 50+40 = <<50+40=90>>90 people
He’s made 10 extravagant gift bags and 20 average bags for a total of 10+20 = <<10+20=30>>30 bags
He hopes 90 people will show up and has already made 30 bags so he needs to make 90-30 = <<90-30=60>>60 more gift bags
#### 60
