this will be in Aussie dollars but you can work out relevant costs based on fuel consumption, cost of insurance and registration. and depreciation costs plus maintenance costs

You find very few cases where the term "costed" is appropriate in English. There are some that say it is not even a proper word, but the would be mistaken. Costed is not used as a past tense variation of the word; rather it is used when describing an action regarding cost, such as when setting the cost of an item. An example:

"The store manager costed the milk at a lower price today."

This seems like an awkward statement, and in reality, you probably will never see it in American English. We would say "priced:" where word costed was used. In areas outside North America however, you may see this usage of the word.

In your sample, the proper usage would be "cost" rather than "costed".

Cost/Sell / Margin can be very confusing it uses the following Account formulas (For Cost = Selling price - ( Selling price / Markup) For Sell = Selling Price =Cost / (1-Margin%))

It is not a pure percentage. Please respond back if you have any other questions.

Let X = cost of TV. Let Y = cost of mini component. You said that both together cost 17500, so X + Y = 17500. You also said that the TV cost 1500 more than the component, so X = Y + 1500. If you combine both equations, you get (Y + 1500) + Y = 17500. Simply reduce this equation to 2Y + 1500 = 17500, which reduces to 2Y = 16000, which reduces to Y = 8000. Using either of the first 2 equations, if Y = 8000, then x must be equal to 9500. The TV cost 9500 and the component cost 8000.
