Discussion Overview

The discussion revolves around calculating the cost of an individual jump ring from a pack of 1,000 that costs $8. Participants explore the conversion between dollars and cents and clarify their understanding of the calculations involved.

Discussion Character

  • Mathematical reasoning

Main Points Raised

  • One participant questions whether the cost per jump ring is calculated as $8 divided by 1,000, leading to confusion about whether the result is in cents or dollars.
  • Another participant provides a mathematical expression to calculate the cost per jump ring, converting the total cost into cents.
  • A later reply confirms the earlier calculation and seeks further clarification on whether the result of $0.008 represents a fraction of a cent or can be expressed as "one tenth of 8 cents per ring."
  • Another participant agrees with the interpretation that $0.008 is equivalent to "4 cents for every 5 jump rings."

Areas of Agreement / Disagreement

Participants generally agree on the mathematical approach to calculating the cost per jump ring, but there is some confusion regarding the interpretation of the result in terms of cents versus dollars.

Contextual Notes

There is a lack of consensus on the interpretation of the decimal result, with participants expressing different ways to conceptualize the cost per jump ring.

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."
