Problem
Penny, a full-time biochemist, loves stock car racing. To feed her passion, she bought a used dirt-track car and has started entering some local dirt-track races. The prize money is pretty small ($1,000 for the winner), but she really is not in it for the money. Penny reported the following income and expenses from her nights at the track:
Prize money $3,580
Transportation from her home to the races 1,630
Depreciation on the dirt-track car 4,180
Entry fees 3,200
Oil, gas, supplies, repairs for the dirt-track car 2,350
Calculate Penny's deduction for the racing expenses assuming that the racing activity is a hobby, and Penny's AGI is $96,620 before considering the prize money.
