Calculating the price per 100 mL of a product can be a useful tool for consumers looking to get the best value for their money, especially when comparing prices of products sold in different volumes. This metric is particularly relevant in sectors such as groceries, cosmetics, and any other market where liquids are sold by volume.
Historical Background
The practice of comparing prices per unit (whether volume, weight, or any other measure) has long been advised by consumer advocates, economists, and budget-conscious shoppers as a means to ensure that consumers are making informed decisions and getting the most out of their purchases.
Calculation Formula
The formula for calculating the price per 100 mL is given by:
\[ \text{PP100mL} = \frac{\text{TP}}{\text{TV}} \times 100 \]
where:
- \(\text{PP100mL}\) is the Price Per 100 mL (\$/100mL),
- \(\text{TP}\) is the total price (\$),
- \(\text{TV}\) is the total volume (mL).
Example Calculation
For instance, if you buy a bottle of lotion for $8.50 that contains 250 mL, the price per 100 mL would be calculated as:
\[ \text{PP100mL} = \frac{8.50}{250} \times 100 = 3.40 \]
This means the price per 100 mL of the lotion is $3.40.
Importance and Usage Scenarios
Understanding the price per 100 mL allows consumers to compare products of different sizes and prices on a like-for-like basis, making it easier to identify the most cost-effective option. This is particularly useful in supermarkets, pharmacies, and online stores where a wide range of product sizes and prices exist.
