During the year, Olivia holds two jobs. After an eight-hour day at the first job, she works three hours at the second job. On Fridays of each week, she returns home for dinner before going to the second job. On the other days (Monday through Thursday), she goes directly from the first job to the second job, stopping along the way for a meal. The mileage involved is as follows: Home to first job 15 First job to second job 18 Home to second job 20 Assuming that Olivia works 48 weeks during the year, how much of her mileage is deductible?
