If Judson paid $500, Kenny contributed 20/100*$500 = $<<500*20/100=100>>100 more than Judson.
In total, Kenny contributed $500+$100 = $<<500+100=600>>600
Kenny and Judson contributed a total of $600+$500 = $<<600+500=1100>>1100
If Camilo contributed $200 more than Kenny, then he contributed $600+$200 = $800
The total amount of money the three contributed for the house painting is $1100+$800 = $<<1100+800=1900>>1900
