Mickey is a 12-year-old dialysis patient. Three times a week for the entire year he and his mother, Sue, drive 19 miles one way to Mickey's dialysis clinic. On the way home, they go 9 miles out of their way to stop at Mickey's favorite restaurant. Their total round trip is 47 miles per day. How many of those miles, if any, can Sue use to calculate an itemized deduction for medical transportation? Use the medical mileage rate in effect for 2016.(Round your "Itemized deduction" answer to 2 decimal places.)
