No, you can't read. Read it again.So he is going to pay 20% for child #1 and 20% to child #2 for a total of 40% of his income? By that logic if he had 5 kids with 5 different women he would pay 100% of his income. That doesnt seem right. Am I missing something here?
If he makes $100/week, then $20 goes to child one, which leaves him with $80. 20% of $80 is $16, which goes to child 2. There is a cap eventually.
But, remember no one told him to have children that he couldn't afford.
