Answer:
Company X:
Sales :
= Gross Profit + Cost of goods sold
= 245 + 330
= $575
Operating expenses:
= Gross profit - Net income
= 245 - 30
= $215
Company Y
Gross profit:
= Sales - Cost of goods sold
= 1,270 - 790
= $480
Net income:
= Gross profit - Operating expenses
= 480 - 525
= $(45)
Company Z
Operating expenses :
= Gross profit - Net income
= 525 - (-20)
= 525 + 20
= $545
Cost of goods sold:
= Sales - Gross profit
= 970 - 525
= $445
