If I sell multiple used cars during the year some for loss some for gain are they kept track of individually or total for the year?

For example if I sell two cars for a profit but two cars at a loss in my taxed on the bottom line for all four cars or am I taxed on the ones with profit and not taxed on the ones that I had a loss. A side question with that if I have a total gain at the end of the year from those sales does that profit go into my overall income and count under the earned income credit guidelines?

Sounds like you are in the business of buying and selling cars which are your inventory so you need to file a Sch C to report the income & expenses.   Any profit will be eligible for the EIC because you will pay  SE taxes on it.
