(a) Amazon's balance in cash at the beginning of the year is $1,085 million

(b) Amazon's total liabilities at the end of the year is $3,914 million

(c) Cost of goods sold for the year is $8,264 million

(d)  Income before income tax for Amazon is $366 million

Explanation:

(a) Beginning cash balance = Ending cash balance - net increase in cash for the year

= $1,104 million - $19 million

= $1,085 million

(b) Total assets = Total liabilities + Total stockholders' equity

$4,417 million = Total liabilities + $503 million

Total liabilities = ($4,417 - $503) million

= $3,914 million

(c) Cost of goods sold = net sales - gross profit

= $10,722 million - $2,458  million

= $8,264 million

(d)  Income before income tax = Gross profit - operating expenses - other expenses

= $2,458 million - $2,062 million - $30 million

= $ 366 million
