Sales â Cost of Sales = Gross Profit â Operating Expenses = Operating Income. Using the operating income margin as an indicator--computed by simply dividing operating income by total sales--will allow you to measure managementâs efficiency in running the business.

Snakes 'hiss' - It sounds just like the sound humans make when they say the letter 'S' out loud. One of my favourite past-times is driving and exploring with my husband (and my dog). In WikiAnswers, I am constantly On the wallaby.
Snakes have a highly developed sense of smell, but they don't use their noses for this. Instead, they taste the air with their tongues, using the damp surface to catch scent particles and carry them to a special organ in the mouth called Jacobson's organ, where they can be identified as food or danger.
