Ryan is self-employed. This year Ryan used his personal auto for several long business trips. Ryan paid $1,590 for gasoline on these trips. His depreciation on the car if he was using it fully for business purposes would be $4,800. During the year, he drove his car a total of 18,800 miles (a combination of business and personal travel). (Do not round intermediate calculations. Round your final answers to the nearest whole dollar amount.) Problem 1-51 Part-a (Algo) a. Ryan can provide written documentation of the business purpose for trips totaling 3,760 miles. What business expense amount can Ryan deduct (if any) for these trips?
