Final answer:
Mark's beginning capital account is $260,000, which includes his cash contribution of $100,000 and the value of the building at $200,000, minus the $40,000 mortgage assumed by the partnership.
Step-by-step explanation:
The question is asking about calculating the beginning capital account for Mark in a new partnership. Mark contributes $100,000 cash and a building worth $200,000, with a mortgage of $40,000 on it. When he contributes the building, the mortgage becomes a liability of the partnership, which means that the value of his contribution must account for this liability.
Therefore, Mark's beginning capital will be calculated as:
- Mark's cash contribution: $100,000
- Value of the building: $200,000
- Mortgage assumed by the partnership: -$40,000
- Total capital account (Cash + Building - Mortgage): $100,000 + $200,000 - $40,000 = $260,000
So, Mark's beginning capital account in the partnership should be option d. $260,000.
