Determine the contribution margin and contribution margin ratio for each segment from the information given. When required, round to the nearest whole millionth (for example, round 5,688.7 to 5,689). Round contribution margin ratio to whole percents for each segment from the information given. Turner Home Box Office Warner Bros. Revenues $ $ $ Variable costs Contribution margin $ $ $ Contribution margin ratio (as a percent) % % %

Segment revenue 49,500       54,100   85,300                   188,900    

Variable costs   (18,810)     (18,935)    (19,619)                   (57,364)

Contribution margin 30,690     35,165           65,681                    131,536
