I just need help with part C. I've continuously worked it out and I keep getting 81,000 but it keeps telling me its wrong.

Stockholders equity $551,000

(b) During the year, total liabilities increased $104,000 and stockholders equity decreased by $60,000. What is the amount of total assets at the end of the year?

Total assets $878,000

(c) If total assets decreased $82,000 and stockholders equity increased $120,000 during the year, what is the amount of total liabilities at the end of the year?
