and/or

[Goodgaii]

100$ per additional item1 and/or item2

Case 1:
100$ per additional item1
and/or
100$ per additional item2

Case 2:
100$ per additional item1
and/or
100$ per item2

Which is correct?

 

[emsr2d2]

They're all wrong. For a start, the dollar sign should come before the numbers. I think you mean something like this:

$100 per additional 1 or 2 items, depending on the case

Case 1:
$100 per each additional item
and/or
$100 per each two additional items


Case 2:
$100 per each additional item
and/or
$100 per each two additional items

(I don't see how it can be $100 for one additional item but the same price for two additional items.)

 

[Tarheel]

Since it's the same amount regardless, you can just say it's $100 for each additional item.

I'm not sure why you're confused, but I know I am. It might help if you rewrite that using shorter, simpler sentences. (Much shorter and much simpler.)

 

[Tarheel]

I think you're having trouble with the word charge. You charge a customer for a product or service. You don't charge the product. (You can charge a cellphone, but that's different.)

You are also confused about the word confuse. If you are confused about something you're having trouble understanding it. If you are confusing you are causing confusion.

1. Two items are installed. The customer is only charged for the second one.

I can't tell you what to charge for. That's entirely up to you.

(Those sentences are not much shorter.)
