How to calculate the cost per roll of cling wrap?

The cost per roll of cling wrap can be calculated using the following formula:

Cost per Roll (C) is determined by:

§§ C = \frac{P}{L \times W} \times A §§

where:

  • § C § — cost per roll
  • § P § — price of the roll
  • § L § — length of the roll (in meters)
  • § W § — width of the roll (in meters)
  • § A § — coverage area (in square meters)

This formula calculates the cost per square meter of cling wrap and then multiplies it by the coverage area to find the total cost for that area.

Example:

  • Roll Price (§ P §): $10
  • Roll Length (§ L §): 30 meters
  • Roll Width (§ W §): 0.3 meters
  • Coverage Area (§ A §): 9 square meters

Calculating the total area of the roll:

§§ \text{Total Area} = L \times W = 30 \times 0.3 = 9 \text{ square meters} §§

Now, calculating the cost per roll:

§§ C = \frac{10}{9} \times 9 = 10 \text{ dollars} §§
