Answer: 9/16/2020
Step-by-step explanation:
Following the information given in the question, it should be noted that the partnership will terminate on 9/16/2020.
A partnership is terminated in a situation whereby there's a transfer of interest such that there's only one partner who then remains. In this casez the termination date will be the date that the interest was sold. Since the sale of interest took place on September 16, 2020, then this will be the termination date.
