Answer: $150,000
Explanation:
Charles's capital account balance is worth $100,000 which is exactly the amount of cash that will be given to him when he exits the partnership. There ware no bonuses to be given as a result.
Because of this, the other partners will keep the same capital account balances as before Charles left. Had it been that they had to pay Charles more than what his account balance was worth, the bonus would have been paid by the two remaining partners from their capital account balances.
