Final answer:
The adjusted basis of the car to Marsha's sole proprietorship would be $30,000.
Step-by-step explanation:
The adjusted basis of the car to Marsha's sole proprietorship would be $30,000. When Marsha transfers her personal use automobile to her business, the adjusted basis of the car carries over. In this case, the adjusted basis is $30,000 since no cost recovery had been deducted for personal use. The fair market value of $16,000 is not relevant for determining the adjusted basis.
