Ryan is self-employed. This year Ryan used his personal auto for several long business trips. Ryan paid $1,600 for gasoline on these trips. His depreciation on the car if he was using it fully for business purposes would be $3,000. During the year, he drove his car a total of 12,000 miles (combination of business and personal travel). Ryan can provide written documentation of the business purpose for trips totaling 3,000 miles. If Ryan does not use the standard mileage rate, what business expense amount can Ryan deduct (if any) for these trips?
