Answer:
the operating margin for the year ended is 5.4%
Step-by-step explanation:
The computation of the operating margin for the year ended is shown below;
Operating Margin = Operating Income ÷ Sales
= $31.3 / $578.3
= 5.4%
By dividing the operating income or earning before interest and taxes from the sales we can get the operating margin
hence, the operating margin for the year ended is 5.4%
