Answer
(a) Total Assets = 320,000 dollars
(b) Total Liabilities = 90,000 dollars
(c) Total Stockholder's liabilities = 600,000 dollars
Work Step by Step
Assets = Liabilities + Stockholder's liabilities
(a)
Total Assets = 90,000 + 230,000
Total Assets = 320,000 dollars
(b)
170,000 = Total liabilities + 80,000
Total liabilities = 90,000 dollars
(c)
Assets = 800,000 dollars
Total Liabilities = $\frac{1}{4} \times 800,000$ = 200,000 dollars
800,000 = 200,000 + Total Stockholder's liabilities
Total Stockholder's liabilities = 600,000 dollars
