How to calculate the cost per pack of light bulbs?

To determine the cost per pack of light bulbs, you can use the following formula:

Cost per Pack (after discount) is calculated as:

§§ \text{Cost per Pack} = \text{Pack Cost} - \left( \frac{\text{Discount}}{100} \times \text{Pack Cost} \right) §§

where:

  • § \text{Cost per Pack} § — the final cost of the pack after applying the discount
  • § \text{Pack Cost} § — the initial cost of the pack
  • § \text{Discount} § — the discount percentage applied to the pack

Example:

Initial Pack Cost (§ \text{Pack Cost} §): $15

Discount (§ \text{Discount} §): 10%

Cost per Pack after Discount:

§§ \text{Cost per Pack} = 15 - \left( \frac{10}{100} \times 15 \right) = 15 - 1.5 = 13.5 §§
