Reasoning and answer: If Judson paid $500, Kenny contributed 20 / 100 * $500 = $100 more than Judson. In total, Kenny contributed $500 + $100 = $600. Kenny and Judson contributed a total of $600 + $500 = $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 = $1900.
The answer: 1900
