Historic Burg is an exempt organization that operates a museum depicting eighteenth-century life. Sally gives the museum an eighteenth-century chest that she has owned for 10 years. Her adjusted basis is $55,000, and the chest's appraised value is $100,000. Sally's adjusted gross income is $300,000. Calculate Sally's charitable contribution deduction if Historic Burg is:
a. A private operating foundation (deduct FMV, 30% AGI limit).
b. A private nonoperating foundation (deduct basis, 50% AGI limit).
