How to calculate the cost per use of a tube of toothpaste?

The cost per use can be calculated using the following formula:

Cost per Use (C):

§§ C = \frac{P}{U} §§

where:

  • § C § — cost per use
  • § P § — price of the toothpaste tube
  • § U § — number of uses

This formula allows you to find out how much you spend on each use of the toothpaste, helping you make informed purchasing decisions.

Example:

Price of Toothpaste Tube (§ P §): $3.50

Number of Uses (§ U §): 75

Cost per Use:

§§ C = \frac{3.50}{75} \approx 0.0473 \text{ or } 4.73 \text{ cents} §§
