How to calculate the cost per pen from a pack?

To find the cost per pen, you can use the following formula:

Cost per Pen (C) is calculated as:

§§ C = \frac{P - (P \times \frac{D}{100})}{N} §§

where:

  • § C § — cost per pen
  • § P § — price of the pack
  • § D § — discount percentage (if any)
  • § N § — number of pens in the pack

This formula allows you to determine how much you are paying for each pen after accounting for any discounts on the pack price.

Example:

  • Price of the Pack (§ P §): $5
  • Number of Pens in the Pack (§ N §): 10
  • Discount (§ D §): 10%

Cost per Pen:

§§ C = \frac{5 - (5 \times \frac{10}{100})}{10} = \frac{5 - 0.5}{10} = \frac{4.5}{10} = 0.45 §§

Thus, the cost per pen is $0.45.
