Lizette and Louisana are in a private school where the tuition is $5,000 a year per student. The Clarks also pay $1,000 per year per child for after-school care. Jefferson is 19 and is in his second year at the University of South Carolina on a partial football scholarship. The Clarks paid the remaining portion of Jefferson's tuition not covered by the scholarship, which was $3,000. They also paid for Jefferson's room and board, which was $7,500.
