How to Calculate the Cost of One Water Bottle?

To find out how much one water bottle costs, you can use the following formula:

Total Cost Calculation:

§§ \text{Total Cost} = \text{Pack Price} + \text{Shipping Cost} + \left( \text{Pack Price} \times \frac{\text{Tax Rate}}{100} \right) §§

where:

  • § \text{Total Cost} § — the total cost of the pack including shipping and tax
  • § \text{Pack Price} § — the price of the pack of water bottles
  • § \text{Shipping Cost} § — the cost of shipping (if applicable)
  • § \text{Tax Rate} § — the sales tax rate as a percentage

Cost Per Bottle Calculation:

Once you have the total cost, you can find the cost per bottle using the formula:

§§ \text{Cost Per Bottle} = \frac{\text{Total Cost}}{\text{Number of Bottles in Pack}} §§

where:

  • § \text{Cost Per Bottle} § — the cost of one water bottle
  • § \text{Total Cost} § — the total cost calculated above
  • § \text{Number of Bottles in Pack} § — the total number of bottles in the pack

Example:

  1. Given Values:

    • Pack Price (§ \text{Pack Price} §): $10
    • Number of Bottles in Pack (§ \text{Number of Bottles in Pack} §): 6
    • Shipping Cost (§ \text{Shipping Cost} §): $5
    • Tax Rate (§ \text{Tax Rate} §): 5%

  2. Calculate Total Cost:

    • Total Cost: §§ \text{Total Cost} = 10 + 5 + \left( 10 \times \frac{5}{100} \right) = 10 + 5 + 0.5 = 15.5 §§

  3. Calculate Cost Per Bottle:

    • Cost Per Bottle: §§ \text{Cost Per Bottle} = \frac{15.5}{6} \approx 2.58 §§
