Seiko’s current salary is $85,000. Her marginal tax rate is 32 percent and she fancies European sports cars. She purchases a new auto each year. Seiko is currently a manager for an Idaho Office Supply. Her friend, knowing of her interest in sports cars, tells her about a manager position at the local BMW and Porsche dealer. The new position pays only $75,000 per year, but it allows employees to purchase one new car per year at a discount of $15,000. This discount qualifies as a nontaxable fringe benefit. In an effort to keep Seiko as an employee, Idaho Office Supply offers her a $10,000 raise. Answer the following questions about this analysis. Problem 12-41
