What is the Cost of One Jump Ring in a $8 Pack of 1000?

[Enoonmai]

If I get a pack of 1,000 jump rings (for jewelry), and the bag costs me $8, how much is EACH jump ring? is it 8 divided by 1,000, which is .008 cents per ring, or is this .008 dollars, and I move the decimal spaces two to the left to get cents? I m a bit confused... Thanks!

I would write:

$$\frac{\$8}{1000 \text{ jump rings}}\cdot\frac{100\text{ cents}}{\$1}=\frac{4}{5}\,\frac{\text{cents}}{\text{jump ring}}$$

Thank you very much! So the .008 was just .008 "dollars" earlier? $8/1000 = 0.008 Dollars?

Is that the same as saying "one tenth of 8 cents per ring" ?

Yes, and another way to look at it is "4 cents for every 5 jump rings."
