9. The Clarks had always thought that taking extended road trips in an RV would be fun. So, in June 2018, they bought a new Winnebago Deluxe Coach RV for $106,250 [$100,000 (discounted list price) + $6,250 (state sales tax)]. However, it only took Andy and Sarah two weeks on the road to determine that this method of traveling the continental United States was not for them. In August 2018, they sold the RV to a neighbor for $90,000. The neighbor paid $20,000 down and paid the balance of $70,000 in early December 2018. Andy did not charge his neighbor any interest. 10. On May 9, 2000, Andy's father gave him 400 shares of Ragusa Corporation common stock as a birthday gift. The stock cost his father $16,000 ($40 a share) and was worth $20,000 on the date of the gift. In 2012, when the stock was worth $140 per share, Ragusa declared a 2-for-1 stock split. On July 27, 2018, Andy sold 400 shares for $20,000 ($50 a share). For sentimental reasons, Andy kept the remaining 400 shares. Form 1099-B did not report the basis of this property
