1 (3 points) Lisa has a full-time job working for the US defense department. On the side, she decided to invest $15,000 in her brother's used car business because she wanted to help him keep the business afloat. In addition, she works there every weekend: 8 hours on Saturday and 8 hours on Sunday. Her $15,000 investment made her a 50% owner of the company. In the first year that she was a part owner, the company lost $40,000, so her prorated loss was $20,000. How much of that loss is suspended because of passive activity loss rules? $5,000 $15,000 None $20,000 $40,000
