4. Rick, a computer consultant, owns a separate business (not real estate) in which he participates. He has one employee who works part-time in the business. If Rick participates for 500 hours and the employee participates for 620 hours during the year, does Rick qualify as a material participant? If Rick participates for 120 hours and the employee participates for 120 hours during the year, does Rick qualify as a material participant? And why? Jenny spends 32 hours a week, 50 weeks a year, operating a bicycle rental store that she owns at a resort community.

She elects not to group them together as a single activity under the "appropriate economic unit" standard. Please determine whether operating a bicycle rental store and operatinga music store are passive activities and explain. 5
