Bruce operates a coffee stall at the university. On 30 June 2016, he has $400 in his business bank account, the stall and equipment are worth $5200, ingredients on hand cost $60 and paper cups cost $10. Students owe him $120 and he owes his suppliers $370. He also owes his mother $4100, which enabled him to get started.What is Bruce's owners' equity? I am confused that in question ,students owe him $120 belongs to Account receivable or Shareholder's Equity?
