Answer:
1) $400,000
2) $495,000
3) $115,000
Step-by-step explanation:
beginning of 2018:
assets $520,000 = $250,000 liabilities + $270,000 equity
+ $60,000 - $90,000
assets $580,000 = $400,000 liabilities + $180,000 equity
assets $520,000 = $250,000 liabilities + $270,000 equity
-$75,000 + $50,000
assets $495,000 = $175,000 liabilities + $320,000 equity
assets $520,000 = $250,000 liabilities + $270,000 equity
-$100,000 $55,000
assets $420,000 = $305,000 liabilities + $115,000 equity
